The material used for fuse must have low melting point and low specific resistance.
Fuses are electrical safety devices that are used to protect electrical equipment and wiring from damage due to overcurrent conditions.
A fuse is made up of a wire or filament that is enclosed in a protective casing.
When an overcurrent condition occurs, the current flowing through the fuse wire causes it to heat up, and eventually, the wire melts and breaks the circuit, interrupting the current flow and protecting the equipment and wiring.
The wire or filament used in a fuse must be made of a material with a low melting point, so that it can melt and break the circuit quickly in the event of an overcurrent condition.
The wire or filament must also have a low specific resistance, which means that it can carry a relatively high current without overheating or melting under normal operating conditions.
