An 'amp' is a slang expression for ' ampere ', whose correct symbol is 'A'. An ampere is the SI base unit for electric current , and is defined in terms of the force between parallel, current-carrying, conductors due to the magnetic fields that surround them. . WebRep. currentVote. noRating. n…oWeight. A ' volt ' (symbol: 'V') is the SI derived unit for potential difference ( voltage ), and is defined in terms of the energy required to separate electric charge. Potential difference, or voltage, can be thought of as the 'electrical pressure' responsible for causing current to pass through a conductor.. (MORE)
The bass amps are built for low frequencies, guitar amps are meant for higher frequencies. This is apparent in the type of speaker used as well as the equalization section.
Answer 1 No difference, but cold cranking amps is what is in battery to start. Answer 2 Answer 1 is correct so far as amps are amps. However, the ambient temperature to which the battery is exposed greatly affects the amount of amps and rate at which current can be released. Therefore, most batt…eries have specifications on a decal for the cranking amps for which they are capable. The first spec ["Cranking Amps"] is at a "normal" temperature of [I think] 70 degrees F. The second spec ["Cold Cranking Amps] is at freezing [32 degrees F, or 0 degrees C]. Since the battery output is lower at lower temperatures, the Cold Cranking Amps will be less than the Cranking Amps.j3h As per the JIS specification for automotive batteries, Cold Cranking Current in Amps is tested at -18deg C and not at 0deg C. depending on the different Ah capacity, each 12V battery will have different CCA amps and duration The battery will be brought to -18 deg C and then it will be discharged with the specified current, say 350, 400 ,450 A until the voltage on discharge drops down to the specified value. The duration in secs to reach the end voltage is noted and compared with the specified values in the spec. (MORE)
Watts = Amps x Volts. Amps = Watts / Volts. you only need to know two of the three to work out the other. so 230 volts at 10 amps gives 2300 Watts (2.3 kW). 2.3kW at 230 volts draws 10 Amps
Joules versus watts The joule and the watt are closely related units. The joule is a unit of work and energy. It is equal to a newton-meter (N-m). Note that the unit of torque is also the newton-meter, but scientists don't use the word joule when they are talking about torque. The watt is a… unit of power and is defined as a joule per second , so you can see that power is work per unit time. One joule is equal to one watt-second. (MORE)
Although we can't necessarily see electricity, we can measure it by its effects. An ampere, or amp, represents the amount of current in a circuit. Voltage is defined scientifically as the circuit's "potential difference," and can be seen as the amount of "pressure" that drives electricity in a circu…it. Watts are a measure of the use of electrical power, and one watt is equal to one volt multiplied by one amp. Additional Answer The watt is used to measure an AC circuit's true power , whereas a volt ampere is used to measure the circuit's apparent power . Apparent power is the product of current and voltage, whereas true power is the product of current, voltage, and power factor. The true power of an AC circuit is measured using a wattmeter, whereas the apparent power is the product of current and voltage. (MORE)

VA or volt-amps is also volts times amps, the concept however has been extended to AC power. For DC current: VA = Watts (DC current). . In AC if the volts and amps are in phase (for example at a resistive load) then the equation is also: VA=Watts (resistive load) where V is the RMS voltage a…nd A is the RMS amperage. (MORE)
Welll, it's actually a lot like the difference between amile-per-hour and cars, or between an inch and people. -- "Watt" is a unit of measure that describes the rate at which energy is used, or produced, or moved from one place to another. -- "Sunlight" is a small portion of the stupendous amou…nt of energythat the sun produces and pours out in every direction at a humongous rate.

RMS means root mean square and watts means power. What a difference!. Scroll down to related links and look for a neat pressure converter at "Root Mean Square" und knowlege about "Watt". Watts root mean square is the effective value of alternating current electrical power compared to direct cu…rrent power.. Scroll down to related links and look for "Why there is no such thing as 'RMS watts' or 'watts RMS' and never has been".. RMS watts is meaningless, but we use that term as "an extreme shorthand" for power in watts calculated from measuring the RMS voltage. (MORE)
A watt is a measure of power , and a volt is a measure of electrical potential difference . A watt is a volt times an amp. Said another way, power (P, given in watts) is equal to current (I, given in amps) times voltage (E, given in volts). The formula is given here: P = I x E See relate…d questions below.. (MORE)
Here's a good analogy, say the wire is a road, the battery a bread factory and the light a super market, the current would therefore be the rate at which the vans leave the factory, and the voltage would be the amount of bread their carrying (the energy). so amps are the rate at which energy is move…d and volts are the actual level or intensity of that energy. Another analogy - You have a big vat full of water. At the bottom is a valve that is closed. The water represents a potential to do work or the voltage. As you open the valve a little bit some water flows out. This represents current. How much the valve is open represents resistance - the smaller the opening the greater the resistance. Now if you had a water wheel near the valve and the outflow of the vat caused the wheel to turn; and if the wheel were connected to a generator you would have a miniature hydroelectric system and could get some work done. Volt is the unit to measure voltage or potential difference of a circuit. Whereas amps or amperes is the unit to measure current flowing in the circuit. they are definitely not the same but two different physical quantities. (MORE)
60 watts. This means that the 40 watt bulb uses less electricity but it also produces less light.
Answer . The volt is a measure of electric potential difference or electromotive force.. The watt is a unit of power which measures a rate of energy use.. Scroll down to related links and look at "Electrical voltage V , amperage I , resistivity R , impedance Z , wattage P ".
A volt is the amount of electricity available in the circuit - Picture a pail filled with water. An Amp is the rate that electricity travels through the circuit - picture a hole in the pail of water - the rate that water escapes from the pail of water is amperage
Watts is the product of amps and volts. It's amps times volts.. The watt (W) is a measure of power (P). It's the SI unit of power, actually, and it's a joule per second. The volt is a measure of electrical potential difference, and is the SI (derived) unit of electromotive force, or EMF (E). Voltag…e, which is measured in volts (V), is the force that drives electron current flow (I), which is measured in amps (A).. In relationship to the volt, the watt is current flow times voltage, or, said another way, a watt is amps times volts. As regards watts and volts, they are "linked" by current. Let's look at the expressions:. Power = Current x Electromotive force => P = I x E. Power (in watts) = Current (in amps) x Electromotive force (in volts). Voltage is a measure of electric potential, in joules per coulomb. Watts is a measure of energy transfer rate, in joules per second. To complete the answer, amperes is a measure of charge transfer rate, in coulombs per second, which is why voltage (joules per coulomb) time amperes (coulombs per second) is watts (joules per second).

Both are used to measure power . The horsepower is simply the Imperial unit for power, whereas the watt is the SI unit for power, where one horsepower is equivalent to 746 watts. In North America, it is traditional to measure the output power of an electric motor in horsepower, while the wa…tt is used to measure its input power . Elsewhere in the world, the watt is used to measure both input power and output power. (The difference between output power and the input power is due to losses, such as heat transfer, friction, windage [air resistance], etc.) Outside North America, the output power of a car engine is now measured in kilowatts rather than in horsepower.

We know that Power = Voltage(V) X Current(I) and power is measured in terms of watts as well as volt-amperes. However, for AC circuits, based on the observation that the voltage considered is often an average measure, VA often tends to be a far higher number as compared to the actual "wattage". B…ased on some information I found at the Argonne national laboratory site: the explanation found was: 1 joule = the energy generated when 1 ampere of electrical current, passes through an electrical potential drop of 1 volt. Energy = Volts x Current. 1 watt = 1 joule/second. So joules is a quantity of energy, and watts is the RATE of generation of energy. Watt = Energy / second. (MORE)
A volt is one individual unit of measurement, used in the formula to calculate the watt, which is overall power The equation is simple: W = V*A W = Power In watts A = Amperes (Amps) V = Voltage (Volts)
A miliamp is one one thousandth of an ampere. So, the difference is that a miliamp is much smaller than an ampere.
The watt is the SI (metric) unit of measurement for power, whereas the horsepower is the Imperial unit for power. Either unit can be used to measure power, although the horsepower is considered archaic in most countries outside North America. For example, most European car manufacturers now ra…te their engines in kilowatts rather than in horsepower. Further Note: The horsepower is still common in the UK, for internal-combustion engines and electric motors. It equals 33000ft-lbs/hour, or 746W. When the 4W per HP error is insignificant, approximating 1 HP to 750W simplifies converting the units. I have seen a peculiar unit quoted in car reviews in the British press, the "kp" (kilopoule) - literally "1000 hens". It's not a standard unit of power in any real system, and I have not seen any conversion for it, but it may emanate from the French car makers. (MORE)

Liken volt and amp to a water in a pipe. Voltage is the water pressure in the pipe and amperage is the water flow through the pipe. They are two completely different electrical units.
Amps are units of current, watts are units of power. Watts are the product of Amps times Volts. Watts = Amps x Volts.
Watts is the product of amps times volts. If you are asking how many watts can be put on a 15 amp circuit breaker then 15 x 120 = 1800. This will probably trip the breaker because it is close to the breaker threshold. So lets say 1600 watts.

None. The ampere is the unit for electric current, while the watt is the unit for power. They are two different quantities, so their units of measurement are unrelated.
How is it possible on the same AC plug to have different relationships of watts and amps measured with a killawatt device one at 147 watts 2.7 Amps and the other at 241 watts 2.4 amps both 117v?
It looks like the 147 watt 2.7 amp specification does not make sense since Power should equal Current X Voltage. The current specified is probably startup current for the motor. Otherwise, it is perfectly acceptable to have two or more devices with different current and power ratings to be connected… to the same voltage since they are connected in parallel.. --. Thanks for the responses, after some further testing I have found that the power factor of the pumps is different and that for AC it is not currentxvoltage but current*voltage*power factor. (MORE)
Amps are just a general measurement of electric current in any application, whereas the term cranking amps are specific to automotive / starting battery applications.

A regular guitar amplifier is generally just the amp head itself (no speaker box), while a combo amp contains the amplifier and the speaker all in one containment box.
Amp is the measure of electric charge per unit of time. Horse power is the measure of the output of machinery, such as piston engines, turbines and electric motors.
' Hz ' is the symbol for ' hertz ', the SI unit for frequency -equivalent to a 'cycle per second'. The frequency of your supply is 50 Hz in Europe, or 60 Hz in North America. The ' watt ' is the SI unit for power , which is the rate at which your electrical appliances use energy.
It is the rating of how much current you can deliver to loads on a circuit. For example, if you had 10 outlets on 20 A service that is what you could run from the outlets on a circuit. This is a total capacity and not the capacity of each outlet on the circuit. If you plugged something into an outle…t that drew 20 A you wouldn't be able to run anything on other outlets. In a lighting circuit two 60 W incandescent bulbs draw one amp. Therefore, on a 15 A lighting circuit you could have a maximum of thirty 60 Watt bulbs. Usually you try and stay at about 80% of rating so practically you could have 24 bulbs. ponypomp; 5 amps. A 15amp breaker is used with 14ga romex wire, designated in homes for lighting. Common practice. A 20amp breaker is used with 12ga romex wire ,designed for the outlets in a home. Common practice. Just wanted to add this to the great post above. (MORE)
They both measure the amperes in a circuit. If you go to the store and ask for an ammeter you will get a meter that with the right circuitry attached will measure amps. That little meter on the front of a battery charger is an ammeter. If you purchase a piece of equipment that measures the curre…nt in a circuit you should get an amp meter. Answer An 'ammeter' is an instrument for measuring current. An 'amp meter' is an incorrect term for an ammeter. (MORE)
A guitar amp is usually used to amplify a six string electric guitar while a bass amp is usually used to amplify an electric bass guitar. The main difference is in the circuitry - solo guitars and bass guitars need different tone-shaping to sound good. Usually bass amps are tailored for the lower fr…equencies while guitar amps are made to sound great in the midrange. Most of the time bass amps have less gain than guitar amps. If we're talking about combo amps (amps that come with a built-in speaker), they have different kinds of speakers built-in. Also, bass amps are usually higher in wattage as low tones need more amplifying to cut through music well. (MORE)
40 watts of consumed power. The light output may be greater with one compared to the other, but wattage alone does not give us that information. Electric heaters, for example, consume 1500 watts of power and produce almost no visible light. Check the Lumen's. That is where the difference is. Curr…ent draw and light output. A 60 watt bulb uses 60 watts of electricity (i.e. it converts 60 joules of energy per second), a 100 watt bulb converts 100 joules per second. Electrical power is measured in watts. Since a 60 watt bulb pulls less energy to it than a 100 watt bulb the 60 watt bulb will not be as bright. Resistance. Just in the amount of power used and the brightness of the bulb. The 60 watt bulb might be a bit smaller. (MORE)
Volt-Amp is apparent power, in direct current Volt x Amps = power with unit of Watt.

The higher the ampacity of a circuit, the greater the load can be that is applied to that circuit.
The ampere is the unit of measurement for electrical current in coulombs per second, while the volt is the unit of measurement for electrical potential in joules per coulomb.
When you first turn on a motor it is starting from a static position and more current is required to get the motor up to speed (Starting current) than to keep it running (running current). Since watts equals amps times voltage you can see the difference in wattage is related to current. If you look …at watts as work being done it is obvious that it requires more work to get the motor running than to keep it running. (MORE)
Amps is a measure of current flowing in a circuit. Volt-Amps or (VA) is a measure of power and is equivalent to wattage for a pure resistive load.
In a DC circuit, the power in watts is the volts times the amps. Inan AC circuit, the volts times the amps is called the VA, and thepower in watts is the VA times the power factor, which is 1 forsome appliances but less than 1 for others. volt-amps, or current, is only one variable of any circuit;… wattagewould be the product of current times voltage, a.k.a. power Answer In purely-resistive AC circuits, the load current and supplyvoltage are said to be in phase with each other, and the product ofthese two quantities is called the true power of the load,expressed in watts . If the AC circuit is not purely resistive, then it isdescribed as being reactive , and the load current eitherlags or leads the supply voltage. In this case, the product ofthese two quantities results, not in the true power of theload, but in the apparent power of the load. Todifferentiate between apparent power and true power, apparent poweris measured in volt amperes ( V . A ) while truepower is measured in watts (W). The cosine of the angle by which the load current leads or lags thesupply voltage in reactive loads is called power factor , andhas to be taken into account when calculating the true power of thecircuit -so, in this case, true power is the product of supplyvoltage, load current, and power factor. To summarise, volt amperes are used to measure the apparent powerof a reactive load, while watts are used to measure its true power. (MORE)

Watts is smaller than kilowatts. watts is unit of power and kilowatts hour is unit of energy. Electrical devices are specified in watts where as electrical bill is for kilowatt hr use.
No difference in case of DC. In case of AC Watt refers to Power which includes the factor of power factor. VA does not include power factor.
Amp is the unit of Electric Current where as Joule is a unit ofenergy. 1 Amp is equal to 1 coulomb per second but 1 Joule is equal to 1newton- metre.
Volts is the unit of Voltage, denoted by 'V'. Watts is the unit of power consumed, denoted by 'W'. As per Indian Standards we are available with 230V single phase connections. And the incandescent bulbs calibrated with some 40W, 60W, 100W shows how much power will it consume for an hour of c…onsumption. Means a 40W bulb will draw 40W power on lighting it for an hour.
