Solve Q no.5
5. (a)State the condition for resonance to occur in series LCR a.c. circuit and derive an expression for
resonant frequency. Mention the factors on which the resonant frequency of a series LCR circuit
depends. Plot a graph showing variation of impedance Of series LCR with frequency of an ac source.(b)
Draw a plot showing the variation of the peak current with frequency of the a.c. source used. Define
quality factor Q of the circuit​
Dear Student,
The quality factor is the measure of "selectivity" of an AC resonant circuit. Resonant circuits are used to respond selectively to signals of a given frequency while discriminating against signals of different frequencies.
