Resonance occures in a series LCR circuit when the frequency of the applied emf is 1000 Hz.

Resonance in series LCR circuit

In a series LCR circuit, at resonant frequency.

An alternating e.m.f. is applied to a series L-C-R circuit. If the frequency of the applied e.m.f. is more than the resonant frequency of the circuit then the circuit will act as
