NEET Physics (general) MCQ Question
Type: MCQ-numerical-Medium-Class 12
In an LC circuit with an initial charge q_0 on the capacitor, what is the expression for the energy stored in the inductor at time t?
A
0.5 * L * (q_0 * ω * sin(ωt))^2
B
0.5 * C * (q_0 * cos(ωt))^2
C
0.5 * L * (q_0 * ω * cos(ωt))^2
D
0.5 * C * (q_0 * sin(ωt))^2
Correct Answer
Option A
Detailed Explanation
The energy stored in the inductor at time t is given by 0.5 * L * i(t)^2, where i(t) = -q_0 * ω * sin(ωt).
