Question

At resonance, the phase angle for RLC series resonance circuit equals

Answer 1

Series Resonance. The resonance of a series RLC circuit occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are 180 degrees apart in phase. The sharp minimum in impedance which occurs is useful in tuning applications.

Answer 2

At resonance Inductive and capacitive are equal so phase angle become zero acc to formula given below
