Question 317: AC fundamentals

Question

In LCR resonant circuit, the current and voltage have phase difference

Accepted Answer

In a series LCR circuit
at resonance
, the inductive and capacitive reactances cancel each other out completely. As a result, the net reactance is zero, making the circuit purely resistive. In a purely resistive circuit, the current and voltage are
in phase
, so their phase difference is
$ \boxed{0}. $
Therefore, the correct answer is:
(D) zero.
