How to convert electrical voltage in volts (V) to electric power in kilowatts (kW).
You can calculate kilowatts from volts and amps, but you can't convert volts to kilowatts since kilowatts and volts units do not measure the same quantity.
So The power P in kilowatts (kw) is equal to the voltage V in volts (V), times the current I in amps (A) divided by 1000.
P(kW) = V(V) × I(A) / 1000
So kilowatts are equal to volts times amps divided by 1000:
kilowatts = volts × amps / 1000
or
kW = V × A / 1000
What is power consumption in kilowatts when the current is 3A and the voltage supply is 25V?
The power P is equal to current of 3 amps times the voltage of 25 volts divided by 1000.
P = 25V × 3A / 1000 = 0.075 kW
What is power consumption in kilowatts when the current is 3A and the voltage supply is 110V?
The power P is equal to current of 3 amps times the voltage of 110 volts divided by 1000.
P = 100V × 3A / 1000 = 0.33 kW
What is power consumption in kilowatts when the current is 3A and the voltage supply is 225V?
The power P is equal to current of 3 amps times the voltage of 225 volts divided by 1000.
P = 225V × 3A / 1000 = 0.675 kW
So The real power P in kilowatts (kW) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V).
P(kW) = PF × I(A) × V(V) / 1000
So kilowatts are equal to power factor times amps times volts:
kilowatt = PF × amp × volt / 1000
or
kW = PF × A × V / 1000
What is power consumption in kilowatts when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 120V?
The power P is equal to power factor of 0.8 times current of 3 amps times voltage of 120 volts divided by 1000.
P = 0.8 × 3A × 120V / 1000 = 0.288 kW
What is power consumption in kilowatts when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 190V?
The power P is equal to power factor of 0.8 times current of 3 amps times voltage of 190 volts divided by 1000.
P = 0.8 × 3A × 190V / 1000 = 0.456 kW
What is power consumption in kilowatts when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 220V?
The power P is equal to power factor of 0.8 times current of 3 amps times voltage of 220 volts divided by 1000.
P = 0.8 × 3A × 220V / 1000 = 0.528 kW
So The real power P in kilowatts (kW) is equal to square root of 3 times the power factor PF times the phase current I in amps (A), times the line to line RMS voltage VL-L in volts (V) divided by 1000.
P(kW) = √3 × PF × I(A) × VL-L(V) / 1000
≈ 1.732 × PF × I(A) × VL-L(V) / 1000
So The kilowatts are equal to square root of 3 times power factor PF times amps times volts divided by 1000.
kilowatt = √3 × PF × amp × volt / 1000
or
kW = √3 × PF × A × V / 1000
What is power consumption in kilowatts when the power factor is 0.8 and the phase current is 3A and the voltage supply is 120V?
The power P is equal to power factor of 0.8 times current of 3 amps times the voltage of 120 volts divided by 1000.
P(kW) = √3 × 0.8 × 3A × 120V / 1000 = 0.498kW
What is power consumption in kilowatts when the power factor is 0.8 and the phase current is 3A and the voltage supply is 190V?
The power P is equal to power factor of 0.8 times current of 3 amps times the voltage of 190 volts divided by 1000.
P(kW) = √3 × 0.8 × 3A × 190V / 1000 = 0.789kW
What is power consumption in kilowatts when the power factor is 0.8 and the phase current is 3A and the voltage supply is 220V?
The power P is equal to power factor of 0.8 times current of 3 amps times the voltage of 220 volts divided by 1000.
P(kW) = √3 × 0.8 × 3A × 220V / 1000 = 0.914kW
