The formula you need to use is I = W/E.
Use this, easier for the average person:
The conversion of Amps to Watts is governed by the equation Watts = Amps x Volts. For example 1 amp * 110 volts = 110 watts
500w = 250v X A amps Therefore: 500w/250v= 2amps
Not enough information to answer this question. Need the 3 phase voltage.
Watts is what you get by multiplying Amps times Voltage, so unless you know Voltage there's no way of telling. For 100 Volts you'd get 250 Watts at 1 amp, for 50 Volts you get it at 5 Amps, and so on.
Using the equation Volts X Amps = Watts, you can take 3000 watts / Volts to get your answer: 3000W/240V = 12.5A or 3000W/120V = 25A So, at 240 volts you will use 12.5 amps for 3000 watts of power. Or at 120 volts you will use 25 watts.
A 30 amp circuit on a 250 volt service could handle up to 7500 watts. That's if it's actually 250 volts coming in. You should check that with your meter.
10 amps 250 volts or 16 amps 250 volts.
For a resistive load Watts = Volta * Amps. Therefore, you have 1/4 amp or 250 Milliamps (250ma)
Depends on the voltage. AMPS X VOLTS = WATTS 250 Watts at 12 V would be about 21 Amps, while 250 watts at 120 volts would be 2.1 amps.
Watts is what you get by multiplying Amps times Voltage, so unless you know Voltage there's no way of telling. For 100 Volts you'd get 250 Watts at 1 amp, for 50 Volts you get it at 5 Amps, and so on.
250 watts divided by 12 volts = amps or around 20 amps
About 2.25 Amps.
The formula you are looking for is W = I x E, Watts = Amps x Volts.
Using the equation Volts X Amps = Watts, you can take 3000 watts / Volts to get your answer: 3000W/240V = 12.5A or 3000W/120V = 25A So, at 240 volts you will use 12.5 amps for 3000 watts of power. Or at 120 volts you will use 25 watts.
The same number as 250 oranges is apples. A watt is a volt times an ampere.
A 30 amp circuit on a 250 volt service could handle up to 7500 watts. That's if it's actually 250 volts coming in. You should check that with your meter.
10 amps 250 volts or 16 amps 250 volts.
For a resistive load Watts = Volta * Amps. Therefore, you have 1/4 amp or 250 Milliamps (250ma)
The mathematical formula to solve this is P= I x R In other owrds the amps x the voltage = watts. 2.2 amps x 120 volts = 264 watts
you would need to know the wattage of each lamp. multiply the lamp wattage x 5 = total watts divide the total wattage / 230 volts (or the voltage you will connect to)= amps example: 250 watts x 5= 1250 watts 1250 watts / 230 volts = 5.43 amps
