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?

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
