Question

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

(a) 0^0

(b) 90^0

(c) 180^0

(d) 360^0

This question was addressed to me during an interview for a job.

This intriguing question originated from The Current in a Series RLC Circuit in section Resonance in AC Circuits of Basic Electrical Engineering

Answer 1

Right option is (a) 0^0

Best explanation: In a series RLC circuit, the phase difference between the current in the capacitor and the current in the resistor is 0^0 because same current flows in the capacitor as well as the resistor.
