Question

The RC circuit shown below has a switch (not shown) which was open until t = 0, at which time the switch was closed (meaning the current in the circuit was zero up until t = 0, and then it started flowing until t = 0). At t = 0 the charge on the positive (top) plate is Qo. The positive direction for current is as indicated on the figure. Building on the previous questions, plot the charge and current as a function of time, for three periods of the oscillation. This time, shade in the times during which the potential electric field is doing positive work in the inductor.
