Key Points About Parallel Resonance
(1)The key points concerning parallel resonant circuits are
(2)The circuit power factor is unity (i.e. 1) so that parallel resonant circuit behaves as a resistance.Since parallel resonant circuit is resistive, it means that
(3) The circuit impedance of a parallel resonant circuit is maximum.
(4) At parallel resonance, the circuit current is minimum and is given by
(5) The resonant frequency fr) of a parallel resonant circuit can be found by equating susceptance of the circuit at fr to zero
