Capacitance of capacitor,
C=100µF=10−4F
Resistance of coil, R=20π
Inductance, L=12.5‌mH=1.25×10−4H
Supply voltage, V=220V
Frequency of AC source,
f=‌

For maximum value of alternating current in L−C−R circuit occurs at resonant condition. i.e XL=XC
∴‌‌Z‌=√R2+(XL−XC)2
‌=√R2+02‌‌(∵XL=XC)
‌=R=20Ω
∴‌‌Imax‌=‌
