Question

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

(a) 0^0

(b) 90^0

(c) 180^0

(d) 360^0

I had been asked this question during an internship interview.

I want to ask this question from Voltages in a Series RLC Circuit topic in division Resonance in AC Circuits of Basic Electrical Engineering

Answer 1

Correct option is (b) 90^0

For explanation I would say: In a series RLC circuit, voltage across inductor lead the current by 90^0 and voltage across resistor is in phase with current so, the phase difference between the voltage across the inductor and the voltage across the resistor is 90^0.
