If power factor = 0, then the current to a load is ______ with the voltage.(a) in phase(b) out of phase(c) 45⁰ out of phase(d) 90⁰ out of phaseI had been asked this question during an interview for a job.This key question is from Apparent Power and Power Factor topic in division Power and Power Factor of Network Theory

Answer»

The CORRECT answer is (d) 90⁰ out of phase

To EXPLAIN I WOULD say: If the power factor = 0, then the current to a load is 90⁰ out of phase with the VOLTAGE and it happens in case of reactive load.
