Let us assume above, that the capacitor, C is fully “discharged” and the switch (S) is fully open. These are the initial conditions of the circuit, then t = 0, i = 0 and q = 0. When the switch is closed the time begins AT&T = 0and current begins to flow into the capacitor via the resistor. Since the initial voltage across the.
