2. Suppose that the switch in an RC circuit with Eo = 0 is closed at time t = 0 when the capacitor has a charge of Qo. The current in the loop for time t≥ 0 is given by I(t) = Ine-t/RC where Io I(0+) = limt → 0+1(t) is the “jump" in the current at time t = 0 when the switch is closed. What is the value of Io? (Hint: I(t) = Q'(t) for all t > 0, where Q(t) = Qoe-t/RC.)
