Problem
A 20μF capacitor is initially charged to 8V with its left plate positive and right plate negative. At t=0 the capacitor is connected across a 4Ω resistor by closing a switch. Indicate the direction of conventional current through the resistor:
(a) just after the switch is closed
(b) after a very long time
