Question

Suppose the initial charge on the capacitor in Exercise 7.7 is 6 mC. What is the total energy stored in the circuit initially? What is the total energy at later time?

Answer 1

Capacitance of the capacitor, C = 30 μF = 30×10⁻⁶ F

Total energy at a later time will remain the same because energy is shared between the capacitor and the inductor.
