Final answer:
A fully charged capacitor does not block the flow of DC current but blocks the flow of AC current. It acts as an open circuit in a DC circuit but continuously charges and discharges in an AC circuit.
Step-by-step explanation:
A fully charged capacitor does not block the flow of DC (direct current) current. This statement is False. When a capacitor is fully charged in a DC circuit, it acts as an open circuit and blocks the flow of current. However, in an AC (alternating current) circuit, the capacitor charges and discharges continuously, allowing the current to flow through.
For example, in an RC circuit with a DC voltage source and an uncharged capacitor, as soon as the switch is closed, current flows to and from the initially uncharged capacitor. 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.
Therefore, a fully charged capacitor blocks the flow of DC current, but not AC current.
