What would happen to the power factor in a purely resistive a.c circuit?
power factor onboard marine emgineering ships
Answers:
Power factor is 1 if the circuit is purely resistive. It only varies if you add some capacitance or inductance into the circuit.
Power factor of 1
A power factor of 0 correlates to a purely inductive circuit, because the true power equals 0.
There is the power factor of zero
In a resistive circuit the power factor is assumed at 1. By adding inductance the power factor will move less than 1, by adding capacitance the p f will move above 1. I say assumed because cable in the circuit does provide a tiny bit of capacitance, for it to be measured it would have to be a very long run.
The power factor of a purely resistive circuit would be unity.
In an inductive circuit (Coils, motors) the current laggs the voltage. In a capacitive circuit the current leads the voltage.
In a resistive circuit the current is in phase with the voltage.
PS That's why there is sometimes a capacitor bolted to a motor.
