Question
In an oscillating LC circuit the maximum charge on the capacitor is Q. The charge on the capacitor when the energy is stored equally between the electric and magnetic fields is -
Options
A.Q / 2
B.Q / √3
C.Q / √2
D.Q
Solution
For LC circuit q = q0 cos ωt,
i = q0ω cos
According to given condition
