Question

The maximum energy stored in a capacitor is?

(a) CV^2

(b) CV^2/2

(c) CV^2/4

(d) CV^2/8

This question was addressed to me in my homework.

I'm obligated to ask this question of Resonant Frequency for a Tank Circuit topic in division Resonance & Magnetically Coupled Circuit of Network Theory

Answer 1

Right option is (b) CV^2/2

Best explanation: The maximum energy stored in a capacitor is CV^2/2. Maximum energy = CV^2/2. As frequency increases the impedance also increases and the inductive reactance dominates until the resonant frequency is reached.
