Electrostatic Potential and Capacitance
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.
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.
