The equation that you are looking for is; amps when kilowatts are known. kW x 1000/1.73 x Volts x pf.45 x 1000 = 45,000/208 x 1.73 x pf. Power factor to use will be .9. 45000/ 324 = 139 amps.
78 amps per phase
8,33 Amps
The equation that you are looking for is Amps = Watts/Volts. There are 6000 watts in 6kW.
Assuming it is a 208-volt line voltage (as normal in 3-phase) the phase voltage is that divided by sqrt(3), or 120 volts. Each phase has to supply 10 kW so the current on each phase is 83.3 amps.
A volt-amp or VA is equivalent to watts, provided the voltage and amperage are in phase. So 1 kilo volt amp is the same as 1 kilowatt. Wattage, or power, is equal to volts times amps. So the original question is effectively nonsense. The number of amps depends on the voltage. If the voltage is 1000 volts, then there's 1 amp in 1 kilo volt amp. If the voltage is 1 volt, then there's 1000 amps. If there's 50 volts, then the amperage is 20 amps. And so on.
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.

Volt amps is the same way of saying watts. This is seen in the formula Watts = Volts x Amps. Using the formula I = W/E we transpose I = 20000/240 = 83.33 amps.

The equation that you are looking for is Amps = Watts/Volts. There are 6000 watts in 6kW.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.
Volt Amps [volts times amps] is used for reactive and apparent power. Watts (dimensionally the same as volt amps) is used to indicate real power.AnswerReactive power is measured in reactive volt amperes (var).

Current in 200kw at 480 volts = 200,000/480 = 416.667 amps
