Electric Circuit Analysis: Unit V: Resonance and coupled circuits

Resonance in ac circuit

An A.C. circuit comprising of R, L and C is said to be in resonance when the applied voltage (source voltage) and the source current are in phase. Thus, at resonance the power factor of the circuit is unity and the circuit acts as purely resistive.

RESONANCE IN AC CIRCUIT

An A.C. circuit comprising of R, L and C is said to be in resonance when the applied voltage (source voltage) and the source current are in phase. Thus, at resonance the power factor of the circuit is unity and the circuit acts as purely resistive.

Resonance in series circuit is referred to as series resonance while resonance in parallel circuits is referred to as parallel resonance or anti-resonance.
