In case of purely inductive circuit, average power = ____ and θ = ______(a) 0, 90⁰(b) 1, 90⁰(c) 1, 0⁰(d) 0, 0⁰I got this question in final exam.This key question is from Average Power topic in portion Power and Power Factor of Network Theory |
Answer» RIGHT choice is (a) 0, 90⁰ To ELABORATE: In case of PURELY inductive circuit, the PHASE angle between the voltage and current is zero that is θ=90⁰. Hence the average power = 0. |
