A fuse is a safety device that protects an electrical circuit from damage caused by overcurrent or short circuit. Fuses are designed to blow or melt when the current flowing through them exceeds a safe level, thus interrupting the circuit and preventing damage to other components.
Fuses are an important part of any electrical system and can help prevent fires and other damage. It is important to know how to remove a fuse from a car in case one blows and needs to be replaced.
