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.
If you know the voltage you can calculate the amps. Ampere I = power P / voltage V.
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.
For a resistive load Watts = Volta * Amps. Therefore, you have 1/4 amp or 250 Milliamps (250ma)
The same number as 250 oranges is apples. A watt is a volt times an ampere.
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.
Use the formula A = W/V, where A is amps, W is watts and V is voltage.
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
9000 watts is zero amps. Amps are the product of amps times volts. Without a voltage stated an answer can not be given. I = W/E, Amps = Watts/Volts.
There are zero watts in 730 amps. Watts is the product of amps times volts. As you can see without a voltage no answer can be given.
Watts = Volts * Amps Therefore: 70 Watts / 13.8 Volts = 5.07 Amps
