Question

At t = 0 the switch S is closed with the capacitor uncharged. If C = 30 micoF, rmf= 50 V, and R = 10 k, what is the potential difference across the resistor as soon as the switch is closed?

Answer 1

assuming they are in series, the entire voltage appears across the resistor immediately because the capacitor has to build up charge on its plates to have a voltage. C= charge / voltage where charge = integral of current over time
