What is φ in terms of voltage?(a) φ=cos^-1V/VR(b) φ=cos^-1V*VR(c) φ=cos^-1VR/V(d) φ=tan^-1V/VRThe question was asked in quiz.The query is from Resistance and Inductance in Series in portion Single Phase Series Circuits of Basic Electrical Engineering

Answer» RIGHT choice is (c) φ=cos^-1VR/V

Easiest EXPLANATION: From the voltage TRIANGLE, we get cosφ= VR/V.

Hence φ=cos^-1VR/V.
