Philoid · Accepted Answer

Given: resistance R = 300Ω,

Capacitance of capacitor C = 20 μF,

Inductance of inductor L = 1.0 Henry,

Voltage across the circuit ϵ_rms = 50 V and

Frequency v = 50/π Hz

Then the rms current across the circuit

Where Z is impedance in the circuit

Then,

Electric energy stored in capacitor will be

Magnetic field energy stored in the coil will be
