Here's why:
* Melts or breaks: Fuses contain a thin wire made of a material with a low melting point. When the current exceeds a predetermined value, the wire heats up and melts, interrupting the circuit.
* Predetermined maximum value: Fuses are designed with a specific "amp rating" which indicates the maximum current they can handle safely.
Fuses are essential safety devices in electrical systems because they protect against overloads and short circuits. They prevent damage to equipment and reduce the risk of fire.
