Question

what is fuse wire made of and why​

Answer 1

Explanation:

Fuse wire is made up of tin pkayed copper wire ... because it has low melting point .

Whenever excess current pass then it melts and breaks the circuit...

Answer 2

Answer:

Fuse wire is made up of alloys.

Explanation:

Fuse are used to break the circuit if there is excess flow of current in the circuit. When excess current flows through the circuit the fuse wire melts and breaks the circuit. Fuse wore are made up of alloys because when alloys have greater resistance then metals and lower resistance then non-metals. So they allow the flow of the current through the circuit. Also when there is excess flow of current fuse wire allows only specific amount of current to flow and the remaining current makes the fuse wire melts and break the circuit.
