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.
