Q7.11 Figure shows a series LCR circuit connected to a variable frequency source. , , .
(a) Determine the source frequency which drives the circuit in resonance.
Given,
Variable frequency supply voltage = 230V
Inductance
Capacitance
Resistance
a) Resonance angular frequency in this circuit is given by :
Hence this circuit will be in resonance when supply frequency is 50 rad/sec.
