Subject and UNIT: Electric Circuit Analysis: Unit V: Resonance and coupled circuits

Consider a circuit through which the current changes. So, the flux linking with the circuit also changes. According to Faraday's law of induction an e.m.f. is induced in the circuit. This e.m.f. is equal to rate of change of flux linkage.

This is series to parallel conversion. Parallel to series conversion is very easy and direct.

Resonance circuits

Subject and UNIT: Electric Circuit Analysis: Unit V: Resonance and coupled circuits

Circuits which exhibit more than one resonant frequency are called multiple resonant circuits.

Resonance circuits
