A series LCR circuit is made by taking
`R = 100 Omega, L = (2)/(pi)` and `C = (100)/(pi) mu F`. The
series combination is connected across an a.c. source of 220 V, 50 Hz. Calculate impedance of the circuit and peak value of current flowing n the circuit. What is power factor of the circuit ?
Compare it with one at resonance frequency.
