Which statement correctly describes what happens when a switch is closed in a circuit?

Explanation:
When a circuit is complete, current can flow. Closing the switch completes the loop, allowing charges to move through the circuit from the power source to the load and back. The switch isn’t a source of energy—it just makes the connection. The actual current depends on the source voltage and the circuit’s resistance, described by Ohm’s law (I = V/R). So, when the switch is closed, current runs through the circuit.
