What is the difference between amps and watts?
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). Voltage, 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).
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 volta…ge considered is often an average measure, VA often tends to be a far higher number as compared to the actual "wattage". Based 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.
Watts is the product of amps times volts. W = A X V. Electricially put W=IxE where w= watts, I= amps, E= volts. watts = unit of power . amps or ampere = unit of electric cur…rent . volts = unit of voltage supplied See also: http://www.wisegeek.com/what-is-the-difference-between-an-amp-volt-and-watt.htm
Amps are units of current, watts are units of power. Watts are the product of Amps times Volts. Watts = Amps x Volts.
kva is an apperent power which is ac,depends on phaseangle eg-e=25cos wt.while watt is a true power which is dc eg-p=vi
Watts are the units for Power while Amps or Amperes are the units for Current.
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.
Amps are just a general measurement of electric current in any application, whereas the term cranking amps are specific to automotive / starting battery applications. Cranking… amps is a measure of the maximum current a car/ starting battery can produce in normal temperatures for 30 seconds before the battery voltage drops too much.
The relationship is, a watt is the product of amps x volts.
Volt-Amp is apparent power, in direct current Volt x Amps = power with unit of Watt. For Alternate Current Volt-Amp is generally different from real power because the power su…pply in wave form and might be out of phase and portion of energy is not usable. Volt-Amp is always higher or equal to real power in AC.
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 fa…ctor, 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.
Power is a quantity , and the watt is its unit of measurement .
volts is the unit of votage while watts is the unit of power
Watts are volts multiplied by current while volts are theelectrical potential difference.
Watts = Volts / Ohms Watts = Volts x Amps
