What are the specific effects of a fuse in an appliance?
A fuse is a safety device for electrical wiring and electrical equipment.
When the line is overloaded or the short-circuit current increases, the fuse is dissolved to cut off the current, protect the circuit and electrical action.
If they are replaced by copper, iron, aluminum wire, their melting point is greater than or equal to the melting point of the wire, it will not be able to cut off the current. Burn a circuit or appliance, so copper, iron, aluminum wire cannot be used instead of a fuse
