Final answer:
If the wire in an electric circuit breaks, the electric current will not flow, making the circuit incomplete.
Step-by-step explanation:
If the wire in an electric circuit breaks, the electric current will not flow. The wire is a crucial part of the circuit, providing a complete path for the current to travel from the positive terminal to the negative terminal of the battery. When the wire breaks, the circuit is interrupted, and the flow of current is stopped.
For example, imagine a simple circuit consisting of a battery, a switch, and a light bulb connected by conducting wires. If the wire connecting the battery to the light bulb breaks, the circuit is incomplete, and no current will flow, resulting in the bulb not lighting up.
