3.3 RESONANCE IN AC CIRCUITS
In ac circuits resonance occurs when two independent energy storing devices
are capable of interchanging energy from one another. For example,
inductance and capacitance are the two energy-storing devices or elements of
an ac circuit, which may create a condition of resonance.
Resonance occurs in other systems also, like in a mechanical system,
where mass and spring are the two energy-storing elements and they may
create a condition of resonance. Mass stores energy when in motion
