Which component would you typically use to protect against overloads in electrical circuits?

The component typically used to protect against overloads in electrical circuits is a fuse. A fuse is designed to interrupt the flow of electricity when the current exceeds a predetermined level, thus preventing excessive heat and potential damage to the electrical components and wiring in the circuit. When a circuit experiences an overload, the fuse element melts or breaks, creating an open circuit and stopping the flow of current. This action helps to safeguard devices and personal safety by reducing the risk of fire and damage caused by overheating.

Other components mentioned serve different purposes in electrical circuits. For instance, a transformer is used to change voltage levels through electromagnetic induction, while a resistor is used to limit current flow or divide voltage in a circuit. A capacitor stores and releases electrical energy but does not provide overload protection. Therefore, a fuse is the ideal choice for protecting against overloads.
