What else can I help you with?
At 12 volts how many watts is 30 amps?
Watts is volts times amps, so 12 x 30 = 360 watts
How do you calculate amperage when given the values of watts and volts?
With an instrument called a multimeter. The single meter incorporates within it a volt meter, an ohm meter and an amp meter. For higher amperages a clamp on amp meter is recommended as the circuit does not have to be opened to take a reading.
.01 amps equal how many volts?
To calculate volts, you also need to know the resistance (ohms) in the circuit according to Ohm's Law. The formula to find volts is V = I x R, where V is voltage, I is current in amps, and R is resistance in ohms. So, to determine volts given 0.01 amps, you'd need the resistance value.
How many volts is 7.5 amps?
Volts and amps are related according to Ohm's law where volts are equal to amps multiplied by resistance. Amps alone won't tell you how much voltage you have. 2.5 amps could have 1 volt or 200 volts it will depend on how much resistance the 2.5 amps sees.AnswerThere are no volts in amperes. They measure different quantities. Your question is like asking, "How many kilometres are there in 2.5 kilograms?" In other words, it is nonesense!
How many amps is in 6000 watts at 240 volts?
Watts divided by volts equals amps so 6000 divided by 120 = 50
How do I figure watts if I know voltage and ohms?
Volts time amps equals watts so watts divided by volts equal amps.
At 12 volts how many watts is 30 amps?
Watts is volts times amps, so 12 x 30 = 360 watts
How do you work out amps in an electrical circuit?
Current symbol I =voltage/resesistance I=V/R for direct current (dc) and for a resistive load in alternating current (ac)

How can you convert amperes in to volts?
Amperes does not convert into volts they are two different values. Become familiar with the following formula and look at the relationships between the values. Volts = Amps x Resistance, Amps = Volts / Resistance and Resistance = Volts / Amps.
How many amps in 120volts and 500ohms?
You use Ohm's Law to make your calculation. Volts = Amps x Resistance Amps = Volts / Resistance
How much current does a line with a voltage of 20 volts and a resistance of 40 Ohms?
The answer is 20 divided by 40, in amps.
.01 amps equal how many volts?
To calculate volts, you also need to know the resistance (ohms) in the circuit according to Ohm's Law. The formula to find volts is V = I x R, where V is voltage, I is current in amps, and R is resistance in ohms. So, to determine volts given 0.01 amps, you'd need the resistance value.
How do you covert watts to amps?
Watts = current x volts, so you have to multiply Kw value by 1000 to get watts, then divide by the applied voltage. examples. 2Kw kettle (U.S) current = 2 x1000 divided by 120, or 16.7 amps 2Kw kettle (UK) current = 2 x1000 divided by 240 or 8.35 amps 100 watt car amplifier current = 100 divided by 12 volts = 8.5amps
What effect are there when resistance is increased in the size of the current?
Current is inversely proportional to resistance. If you double the resistance, you halve the current. Ohm's Law: Volts = Amps * Ohms Solve for Amps: Amps = Volts / Ohms
How do you measur ampere?
You use an "amp gauge" to measure amps in an actual circuit. It is hooked in series with the load. It can be placed anywhere in the circuit as long as it is hooked in series. Mathematically, you have to know the resistance, or wattage and voltage of a circuit. Volts=amps*resistance or amps=volts/resistance, or resistance=volts/amps. Ohms law!
