What else can I help you with?
What if your tutor tells you than an ampere and a volt really measure the same thing?
An ampere and a volt do not measure the same thing. Ampere measures electric current flow, while volt measures electrical potential difference or voltage. Having a clear understanding of the difference between these units is essential in understanding electricity.
Difference between watt and volt-amperes?
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 circuit. Watts are a measure of the use of electrical power, and one watt is equal to one volt multiplied by one amp.Additional AnswerThe 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.
How much does 48 inches equal in feet?
48 inches is equal to 4 feet. This is because there are 12 inches in 1 foot, so dividing 48 by 12 gives you 4 feet.
If two dogs together weighs 36 pounds and Fido weighs twice as much as Rex how much does each dog weigh?
Fido weighs 24 lbs, Rex weighs 12 lbs. This is simple algebra, you figure that if fido weighs twice as much as rex, and assume 'x' is rex's weight, you can figure 2x + x = 36, you can simplify that to 3x = 36. Divide both sides by 3 (because you have 3x) and you get x = 12 (rex's weight)
Is 12 pints greater thanless thanor equal to 3 gallons?
8 pints = 1 gallon 1 pint = 1/8 gallon 12 pints = 12 x 1 / 8 = 12 / 8 = 6 / 4 = 3 /2 = 1.5 gallons So 12 pints is less than 3 gallons
How much is 900 watts?
About as much as 15 typical (60watt each) light bulbs together. Or expressed in horsepower: about 1.2Hp Mains volts and ampere: 230 volt at 3.91 ampere = 900watt 110 volt at 8.18 ampere = 900watt
How many volts in 1 ampere?
That's like asking how many meters in a liter. Ampere and Volt are two DIFFERENT measurements. Ampere is how much electricity you are using, while volts are how much pressure the electricity is under(Think water). If you want to figure out how many amperes your appliance is using you could use this formula: P=UxI (Watt=Volt x Ampere) or U=RxI(Volt=Resistance x Ampere).
Can I use 4.5 volt 2 ampere adaptor instead of 5 volt 2 ampere?
yes you can.
How many amps if there is a 12 volt electrical system and 50 ohms resistance?
0.24 ampere
How much curent flows in a 12-watt radio connected to a 120-volt circuit?
Power = voltage x currentCurrent = power/voltage = 12/120 = 0.1 ampere = 100 milliamperes
How much current flows in a 12 watt radio connected to 120 volt circuit?
A 120V household electrical outlet supplies 12 watts of powerwhen the current is 0.1 Ampere (and the power factor is 100%).
What is is kva?
kVA is kilo-volt-ampere, which is 1000 x volt x ampere. kVA is the unit of apparent power in AC circuits.
What is the ampere rating for a 12 volt 12 watt battery?
Batteries are generally not listed as having watts. And there are a couple of different ampere ratings. But if you're running something needing 12W of a 12V battery it's pulling 1A out of the battery at the moment.
How much current flows through a circuit if the resitance is 4 ohms and there is a12 volt battery?
3 Ampere
How many lights on 12 volt battery?
It depends on the Ampere Hour rating of the battery. But basically just connect as much as you wish but not more than 5 lamps and must be 12v each.
How source of 6 volt gives 1 ampere current and source of 18 volt gives 0.5 ampere at same resistance is it violation of ohms law?
yes
What is the resistance of an electric frying pan that draws 12 amperes of current when connected to a 120 volt circuit?
Given R=? I=12 ampere V=120 Volts equation I=V divided R Solution; R=12 ampere 120 Volts answer (10)
