An uncharged capacitor and a resistor are connected in series to a battery, as shown in the figure above. If V = 14.0 V, C = 5.30 µF, and R = 7.90 x10^5 ?, find the following:
(a) the time constant of the circuit
(b) the maximum charge on the capacitor
(c) the charge on the capacitor after 5.60 s
(d) the potential difference across the resistor after 5.60 s
(e) the current in the resistor at that time
