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 question, plot the charge and current

as a function of time, for three periods of the oscillation.
