Question

When exess electric current flows through the circuit, fuse wire melts and breaks the circuit.

a) Whether heat energy is produced when allowed amount of Current flows in the circult? It Yes Why doesn't the fuse wive break? 2

b) why does fuse wire melt when exess electric current flows through the Circuit?​

Answer 1

Answer:

Fuses are sacrificial devices used to protect much more expensive electrical components from the damaging effects of overcurrent. ... When too much current flows through the low resistance element of the fuse, the element melts and breaks the circuit
