At t=0, the switch is closed, and the curve below shows the potential V across t

Question

At t=0, the switch is closed, and the curve below shows the potential V across the capacitor as a function of time t.

A capacitor C is charged to an initial potential of 70.0 V, with an initial charge of Q0. It is in a circuit with a switch and an inductor with inductance L = 4.43

At t=0, the switch is closed, and the curve below shows the potential V across the capacitor as a function of time t. 1.Calculate the energy in the circuit after a time of 14 periods. Note that the curve passes through a grid intersection point. 2.Calculate the time required for 91% of the initial energy to be dissipated. A capacitor C is charged to an initial potential of 70.0 V, with an initial charge of Q0. It is in a circuit with a switch and an inductor with inductance L = 4.43 A 10^-2 H and resistance RL.

Explanation / Answer

The curve gives you two important pieces of information:

The period and the amplitude of the sine wave.
