The electric fuse
Electric fuse is used as safety device for the protection of electric circuits and appliances due to short circuiting or overloading of the circuit.. The electric fuse is a piece of wire having a very low melting point and high resistance.When a high current flows through the circuit due to short circuit or overloading, the fuse wire gets heated and melts. The circuit is broken and current stops flowing thus save the electric circuit and appliance form damage.
Capacities of fuse wire
The fuse for domestic purposes are rated as 1A, 2A, 3A, 5A, 10A and 15A.
Characteristics of fuse wire
1. Low melting point
2. High resistance
Fuse wire are made up of pure tin or made of an alloy of copper and tin.
