DC volts to watts calculation formula

So The power P in watts (W) is equal to the voltage  V in volts (V), times the current  I in amps (A).

P(W) = V(V) × I(A)

Example 1

What is power consumption in watts when the current is 4A and the voltage supply is 15V?

Answer: the power P is equal to current of 4 amps times the voltage of 15 volts.

P = 15V × 4A = 60W

Example 2

What is power consumption in watts when the current is 3A and the voltage supply is 25V?

Answer: the power P is equal to current of 3 amps times the voltage of 25 volts.

P = 25V × 3A = 75W

AC single phase volts to watts calculation formula

So The power P in watts (W) is equal to the power factor  PF times the phase current  I in amps (A), times the RMS voltage  V in volts (V).

P(W) = PF × I(A) × V(V)

Example 1

What is power consumption in watts when the power factor is 0.8 and the phase current is 3A and RMS voltage supply is 120V?

Answer: the power P is equal to power factor of 0.8 times current of 3 amps times voltage of 120 volts.

P = 0.8 × 3A × 120V = 288W

Example 2

What is power consumption in watts when the power factor is 0.8 and the phase current is 3A and RMS voltage supply is 150V?

Answer: the power P is equal to power factor of 0.8 times current of 3 amps times voltage of 150 volts.

P = 0.8 × 3A × 150V = 360W

AC three phase volts to watts calculation formula

Calculation with line to line voltage

So The power P in watts (W) 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).

P(W) = 3 × PF × I(A) × VL-L(V)

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

Example 1

What is power consumption in watts when the power factor is 0.8 and the phase current is 3A and the RMS  voltage supply is 120V?

Answer: the power P is equal to power factor of  0.8 times current of 3 amps times the voltage of 120 volts.

P(W) = 3 × 0.8 × 3A × 120V = 498W

Example 2

What is power consumption in watts when the power factor is 0.8 and the phase current is 3A and the RMS  voltage supply is 150V?

Answer: the power P is equal to power factor of  0.8 times current of 3 amps times the voltage of 150 volts.

P(W) = 3 × 0.8 × 3A × 150V = 623W

Calculation with line to neutral voltage

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

P(W) = 3 × PF × I(A) × VL-N(V)
