Watts equal amps times voltage, so Watts divided by voltage (120), = 125 amps. With 240 volts, the amperage would be 1/2 or 62.5 amps. Are you referring to a 1500 watt heater? In that case it would be 12.5 amps at 120 volts.
watt divided by voltage gives the current
in that case it is 15*1000w/240v gives 6.25A when the power factor is unity.
I=W/V*pf
The above math is wrong. 15kw = 15000 watts. Therefore 15000 / 240 volts = 62.5 amps. If the voltage is 120 volts then the amperage would be 125 amps. For consideration; A 15000 watt generator (15kw), is capable of supplying 125 amps at 120 volts or 62.5 amps at 240 volts.
You need to determine the line voltage and the line current. The 230 V quoted is a phase voltage, and the line current is 400 V. You then use the equation: P = 1.732 x line voltage x line current x power factor, for a balanced load. In this case, for a resistive load, the power factor is unity (1).
So, in this case, to find the line current, we divide the power by (1.732 x line voltage x power factor), which works out at:
line current = 15000/(1.732 x 400 x 1) = 21.28 A
To calculate the amperage, you can use the formula: Amps = Watts / (Volts x sqrt(3)). For a 15kW heater at 230V 3-phase, the amperage would be approximately 28.2 amps.
You will find that answer on the name plate of the water heater. Everyone is different and you should all way check the manufactures specifications.
15000W divided by 230V = 65.21Amps but you have to take other factors into account.
The equation you are looking for is Amps = kW x 1000/1.73 x volts x pf. The power factor will be 1 on an electric heater.

How many amps for 1hp 3phase?
For a 1hp 3-phase motor, the current draw will depend on the voltage supply. Typically, at 230V, a 1hp 3-phase motor will draw around 3.6 amps. However, this value may vary based on the motor efficiency and power factor.
How many amps does a 10kw heater draw that's 3phase 220volt?
To calculate the amperage for a 10kW heater on a 3-phase 220V system, use the formula: Amps = (kW x 1000) / (√3 x Volts). So, Amps = (10 x 1000) / (√3 x 220) = 26.18 amps per phase. Therefore, the total current drawn by the heater is 26.18 amps per phase multiplied by 3, which equals approximately 78.54 amps.

What is the amperage of a 20 HP 240v single phase motor?
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
How do you work out amps of current from 230V connected to 534 ohm resister?
you divide the volts by the ohms
If a heater claims to be 1500 watts how long would it take for that heater to draw 1500 watts?
Watts is the amount of power the heater has and amps would be the draw- if it is a 120 volt heater than the amps would be 12.5 amps and it is instantaneous
How many amps do you need if you have a 480 volt space heater?
The heater should have a wattage rating (very few list amps). Calculate the amps using the wattage and voltage. Amps = Watts/Volts(480).
