The power factor of an AC circuit is 0.5. If the voltage and current are out of phase by 60°, what is the nature of the circuit?
Q1. The power factor of an AC circuit is 0.5. If the voltage and current are out of phase by 60°, what is the nature of the circuit?
Answer: R-L or R-C
Explanation: Power factor = 0.5 implies cos(φ) = 0.5, hence φ = 60°. This indicates the circuit is either R-L or R-C as both can have a phase difference.
