Which term describes a device that interrupts the flow of electricity in case of overloads?

A fuse is a safety device designed to protect electrical circuits from overloads by interrupting the flow of electricity. It consists of a thin wire that melts and breaks the circuit when the electrical current exceeds a predetermined level, effectively preventing potential damage to the circuit and connected devices. This mechanism helps to safeguard against overheating and reduces the risk of fire or electrical failure.

In contrast, a resistor is used to control the flow of current within a circuit but does not interrupt it during overloads. A capacitor stores electrical energy for a short period but does not serve as a protective device against excess current. A transformer is used to change voltage levels in AC circuits and does not function as a protective measure against overloads. Therefore, the fuse is specifically designed to act as a safeguard, making it the appropriate choice for this situation.
