Question: 1 / 400

Which of the following is NOT a common function of a fuse in electrical circuits?

Prevent overheating

Regulate voltage

The function of a fuse in electrical circuits is primarily to protect the circuit by preventing excessive current flow, which can lead to overheating, overloads, and shield against short circuits. In this context, the role of a fuse is to act as a safety device that melts and breaks the circuit when the current exceeds a certain threshold, thus preventing damage to the system.

Regulating voltage, however, is not a function of a fuse. Voltage regulation typically involves devices such as transformers or voltage regulators that control and maintain a desired voltage level in electrical circuits. Fuses do not adjust or control voltage; their sole purpose is to disconnect the circuit when current levels become dangerous. This distinction clarifies why the correct answer focuses on the misconception that a fuse plays a role in voltage regulation, which it does not.
