Final answer:
In an RC circuit, the capacitor discharges through a resistor when the switch is closed.
Step-by-step explanation:
In an RC circuit, the capacitor is connected in parallel with a resistor. When the switch is closed, the capacitor discharges through the resistor. This process occurs because as charge increases on the capacitor plates, there is increasing opposition to the flow of charge by the repulsion of like charges on each plate.
