Question

The material used for fuse has low melting point give scientific reason

Answer 1

Answer:

The melting point of the material used for fuses is low because if the current exceeds the limiting value then the temperature of wire increases and the fuse wire melts and breaks down at that very moment. So, the current stops. This prevents damaging the costly electrical appliances connected through the circuit.

Explanation:

is the answer

Answer 2

Answer:

i.                     A fuse is used to protect a circuit and the appliances connected in the circuit by stopping the flow of an excess electric current. For this, a fuse is connected in series in the circuit.

ii.                    When the current in the circuit passes through the fuse, its temperature increases. When the current exceeds the specified value, the fuse must melt to break the circuit. For this, the material used for a fuse has low melting point.
