The formula you are looking for is I = W/E, Amps = Watts/Volts. Amps = 5000/230 =21.7 amps. The wire size to run this heater would be a #10 copper conductor. The supply breaker would be a two pole 30 amp breaker.
The heater does not have a kilowatt OUTPUT. It uses electricity, but does not make it. The wattage is amps time volts- in this case, 12,000 watts. To get kilowatts, divide by 1,000. That heater has an input of 12 kilowatts.
22.5
The load is a resistive load and as such it is governed by Ohm's law. Current is directly proportional to the voltage and inversely proportional to the resistance. As the voltage goes down so does the current. 2200 watt heater at 220 volts = 10 amps. R = E/I = 220/10 = 22 ohms of resistance in the heater. Now take the 2200 watt heater and using the same formula and at 110 volts. I = E/R, Amps = Volts / Resistance. 110/22 = 5 amps. As you can see ohm's law holds true, the current is inversely proportional to the resistance and as the voltage goes down so does the current. To answer the question, yes a 220 volt heater will run on a 110 volt circuit but at a reduced wattage. W = A x V = 5 x 110 = 550 watts.A 2200 watt heater at 220 volts would draw 1/2 the current of a 2200 watt heater at 110 volts.A 2200 watt heater at 220 volts is 22 ohms of resistance. Resistance would not change with the voltage, current would only be 5 amps (a resistor is a current limiter, it will only let more current through if you apply more voltage not less); but the wattage would only be 550 watts. This would only give you a fourth of the power this heater was designed for! The heater and the wires would have less heat.
At 120 Volts you would draw about 42 amps. At 240 Volts it would be about 21 amps. For 120 Volts you would need 6 AWG and for 240 Volts you would need 10 AWG.
10 Amps. Amps=Watts/Volts
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
100 KW divided by 415 volts is 241 amperes. Power = voltage times current, so current = power divided by voltage.
Current (amps)=Watts/Volts =2000/120 =16.75 =16.75 amps

1.25 A
100 KW divided by 415 volts is 241 amperes. Power = voltage times current, so current = power divided by voltage.
Basically, Power = Current*Voltage Current = Power/Voltage Current = 15/120 Current = 0.125A or 125mA
Check the current draw that is on the label of the ballast.
There are zero amps in 1000 watts. Watts are the product of amps x volts or I = W/E, watts divided by voltage. As you can see, that if no voltage is stated no amperage can be given. Once you find the voltage of the heater then use the following equation, Amps = Watts/Volts to find the current draw of the 1000 watt heater.
The formula you are looking for is I = W/E.
Divide the power rating (in watts) by the voltage (in volts). So if you use a 100 watt light bulb in a typical 110 volt lamp then it will draw 100/110 = .91 amps of current. Or plug a 1500 watt electric heater into a 110 volt wall socket and it will draw 1500/110 = 13.6 amps of current.
