Kilowatts (kW) to amps (A) calculator.

* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12

So The current I in amps (A) is equal to [1000] times the power P in kilowatts (kW), divided by the voltage V in volts (V).

*I*_{(A)} = 1000* *×* P*_{(kW)} / *V*_{(V)}

What is the current in amps when the power consumption is 0.33 kilowatts and the voltage supply is 120 volts?

*I* = 1000 × 0.33kW / 120V = 2.75A

What is the current in amps when the power consumption is 0.33 kilowatts and the voltage supply is 150 volts?

*I* = 1000 × 0.33kW / 150V = 2.2A

So The phase current I in amps (A) is equal to [1000] times the power P in kilowatts (kW), divided by the power factor PF times the RMS voltage V in volts (V).

*I*_{(A)} = 1000* *×* P*_{(kW)} / (*PF* × *V*_{(V)}* *)

What is the phase current in amps when the power consumption is 0.33 kilowatts, the power factor is 0.8 and the RMS voltage supply is 120 volts?

*I* = 1000 × 0.33kW / (0.8 × 120V) = 3.4375A

What is the phase current in amps when the power consumption is 0.33 kilowatts, the power factor is 0.8 and the RMS voltage supply is 150 volts?

*I* = 1000 × 0.33kW / (0.8 × 150V) = 2.75A

So The phase current I in amps (A) is equal to [1000] times the power P in kilowatts (kW), divided by square root of 3 times the power factor PF times the line to line RMS voltage V_{L-L} in volts (V).

*I*_{(A)} = 1000* *×* P*_{(kW)} / (*√*3 × *PF* × *V*_{L-L(V)}* *)

What is the phase current in amps when the power consumption is 0.33 kilowatts, the power factor is 0.8 and the voltage supply is 120 volts?

*I* = 1000 × 0.33kW / (*√*3 × 0.8 × 120V) = 1.984A

What is the phase current in amps when the power consumption is 0.33 kilowatts, the power factor is 0.8 and the voltage supply is 150 volts?

*I* = 1000 × 0.33kW / (*√*3 × 0.8 × 150V) = 1.587A

So The phase current I in amps (A) is equal to [1000] times the power P in kilowatts (kW), divided by 3 times the power factor PF times the line to neutral RMS voltage V_{L-N} in volts (V).

*I*_{(A)} = 1000* *×* P*_{(kW)} / (3 × *PF* × *V*_{L-N(V)}* *)
