Current as a Function of Time for a Circuit
Not what you're looking for?
Let us now consider a different RC circuit. This time, the capacitor is initially charged (q(t) = q_0), and there is no source of EMF in the circuit. We will assume that the top plate of the capacitor initially holds positive charge. For this circuit, Kirchoff's loop rule gives IR + q/C = 0, or IR = -q/C.
Find the current I(t) as a function of time for this circuit.
Express your answer in terms of q_0, C, t, R, and e.

Again i'm totally lost
I know i have to integrate something but i don't know what or how.
Thank you!!!
