Power result in watts:W

DC volts to watts calculation formula

The value of power P in watts (W) is apparently equal to the value of voltage V in volts (V), multiplied by the current I measured in amps (A).

P(W) = V(V) × I(A)

AC single phase volts to watts calculation formula

The value of power P in watts (W) is apparently equal to the value of power factor PF  multiplied by the phase current I measured in amps (A), multiplied with the RMS voltage V measured in volts (V).

P(W) = PF × I(A) × V(V)

AC three phase volts to watts calculation formula

Calculation with line to line voltage

The value of power P in watts (W) is apparently equal to the value of square root of 3 multiplied by the power factor PF times the value of phase current I measured in amps (A), and times the line to line RMS voltage VL-L measured in volts (V).

P(W) = √3 × PF × I(A) × VL-L(V)

            = 1.732 × PF × I(A) × VL-L(V)

Calculation with line to neutral voltage

The value of power P in watts (W) is apparently equal to 3 times the power factor PF times the phase current I in amps (A), multiplied by the line to neutral RMS voltage VL-N measured in volts (V).

P(W) = 3 × PF × I(A) × VL-N(V)

For Example,

Find the value of power consumption in watts if the value of power factor is 0.9 and if the value of the phase current is 2A and the value of RMS  voltage supply is 100V?

P(W) = 3 × 0.9 × 2A × 100V = 200 W
