Question

circumstance that cause high electric current leading to melting of fuse wire​

Answer 1

Answer:

Circumstances are like when the insulating wire breaks, high current flows. Causing melting of fuse wire

Answer 2

$\huge \bigstar \huge \tt \underline\red{ANSWER } \:$

The current in the circuit may increase due to reasons such as short circuit, overload, excess flow of current or any problems in the insulation. As the higher temperature produced in the circuit due to these reasons makes the fuse wire to melt and the flow of current stops.
