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 field is
- Q/2
- Q/√3
- Q/√2
- Q
Correct answer: Q/√2
Solution
At the point where the energy is equally distributed between the electric field of the capacitor and the magnetic field of the inductor, the charge on the capacitor is at a value of Q/√2. This is derived from the relationship between energy stored in the capacitor and inductor, where the total energy remains constant.
