Question

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

(a) 0^0

(b) 90^0

(c) 180^0

(d) 360^0

I had been asked this question in my homework.

My doubt stems from The Current in a Series RLC Circuit topic in portion Resonance in AC Circuits of Basic Electrical Engineering

Answer 1

The correct choice is (b) 90^0

The best I can explain: In a series RLC circuit, voltage across capacitor lags the current in the circuit by 90^0 so, the phase difference between the voltage across the capacitor and the current in the circuit is 90^0.
