what would happen to the power factor in a purely resistive a.c circuit?

Question

power factor onboard marine emgineering ships

Answer 1

Power factor is 1 if the circuit is purely resistive. It only varies if you add some capacitance or inductance into the circuit.

Answer 2

There is theoretically NO power factor correction in a purely resistive circuit. The only power factor correction from a "purely resistive" circuit comes from interactions with capacitance and inductance effects from the "wiring" of the circuitry itself, and the components. The effect is small, but noticeable, higher or lower due to the inheritance capacitive or inductive reactance, which, though negligible in some circuits, has a small effect, nonetheless. In your thoeretically "perfect" circuit, the "power factor" would be 1.0

Answer 3

It would be 1.
