A single phase circuit has an input voltage of 100V. The current is 10A and the circuit has a power factor of 0.5. The true power is
- 50W.
- 1000W.
- 500W.
Explanation from PART66Online
True (real) power in a single-phase AC circuit is P = V x I x power factor = 100 x 10 x 0.5 = 500 W. The 1000 W figure is the apparent power (V x I in volt-amps) before applying the 0.5 power factor.
