AC Wattage Calculator

Find real power in an AC circuit.

Calculated Output

Real power (W) 1,035

Formula: P = V·I·PF

Step-by-Step Breakdown

1. Values used:

2. Voltage = 230 V

3. Current = 5 A

4. Power factor = 0.9

6. Real power = Voltage x Current x Power factor = 230 x 5 x 0.9 = 1,035W

Did this calculator solve your problem today?

The math behind it

P = V·I·PF. With a power factor below 1, real power is less than the apparent V·I.

230 V, 5 A, PF 0.9 → 1035 W.

What if PF = 1?

Then P = V·I, the same as DC power.
