5. [RC Circuits] Consider the circuit shown in Figure 5 attached. As shown, the switch is in position "A" for t < 0, and the circuit has been at rest for a long time. At time t = 0, the switch opens and the capacitor starts to drain across the resistor. (a) When the switch is closed and there is only a direct current (DC) source, the capacitor acts like an open circuit. Find the constant voltage across the capacitor...
