Explanation:

For current to flow in any circuit, it should make a closed loop. If there is any point where the circuit is open the flow of current will stop.

Here as well, when the wires of a circuit will break, circuit will be in open state and stop the flow of current. Once the wires are reconnected, current will start flowing again in the circuit.
