Hi all,
I'm trying to find an expression for the current i(t) as a function of C and V_out (t) after t = 0. I have an answer but still not sure at all if its correct or not.
Here is my answer:
I know that
i(t) = C*dV(t) / dt
V(t) = Ri(t) + V_out (t)
combining them together
i(t) = C-dV_out(t)/dt - dV_out(t) / R
Here is the circuit.
