Under what condition will the current through a series LCR circuit be in phase with voltage?

Text Solution

Verified by Experts

Current through a series LCR circuit will be in phase with voltage, when inductive reactance `(X_(L))` = capacitive reactance `(X_(c))`. The circuit in this case is said to be under resonance. `Z=Z_(min)=R,I=I_(max)`.
