Question

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

(a) 0^0

(b) 90^0

(c) 180^0

(d) 360^0

I had been asked this question in class test.

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

Answer 1

Correct choice is (a) 0^0

The explanation is: In a series RLC circuit, the phase difference between the voltage across the resistor and the current in the circuit is 0 degrees because they are in phase.
