Question

In a series RLC circuit, the phase difference between the voltage across the capacitor and the voltage across the resistor is?

(a) 0^0

(b) 90^0

(c) 180^0

(d) 360^0

This question was addressed to me in quiz.

My question is from Voltages in a Series RLC Circuit topic in portion Resonance in AC Circuits of Basic Electrical Engineering

Answer 1

Right answer is (b) 90^0

Explanation: In a series RLC circuit, voltage across capacitor lag the current by 90^0 and voltage across resistor is in phase with current so, the phase difference between the voltage across the capacitor and the voltage across the resistor is 90^0.
