Electrostatic Potential And Capacitance

Question
CBSEENPH12037993

State the condition under which the phenomenon of resonance occurs in a series LCR circuit. Plot a graph showing variation of current with frequency of a.c. source in a series LCR circuit. 


Solution
Resonance occurs in a series of LCR circuit when
                              XL = Xc

The graph showing the variations of current with frequency of a.c. source in a series LCR circuit is given below.
