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.
Decibels
1540 watts
2.4705 watts/hour
250 ÷ 10 = 25.
To calculate how many 4000s are in 1 million, you would divide 1,000,000 by 4,000. This would give you 250, meaning there are 250 occurrences of 4000 within 1 million.
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.
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.
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
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.
Use the formula A = W/V, where A is amps, W is watts and V is voltage.
To determine the amperage drawn by a 250-watt metal halide bulb, you can use the formula: Amps = Watts / Volts. Assuming the bulb operates on a standard voltage of 120 volts, it would draw approximately 2.08 amps (250 watts / 120 volts). If it operates at 240 volts, it would draw about 1.04 amps (250 watts / 240 volts). Always check the specific voltage rating for accurate calculations.
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.
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
