Question

When a capacitor is fully charged in a DC circuit, does it act like an open switch or a closed wire?

Accepted Answer

When a capacitor is fully charged in a DC circuit, it acts like an open switch. A capacitor is essentially two metal plates with a gap between them that stores electrical energy. While it is charging, electricity flows into it to build up that energy. Once it is full, it has no more room to take in electricity, so the flow stops completely. Because no electricity can move through it anymore, it is exactly like a break in the wire or a switch that has been turned off. Think of it like a sponge that has finished soaking up all the water it can hold; once it is full, no more water can pass through it.
