Question

True or False The resistance of fuse wire is low and melting point is high.

Answer 1

Answer:

true..................

Answer 2

Asseriton is true but reason is false Fuse wire must have high resistance because in series current remains same, therefore according to Joule's law H=i2Rt4.2, heat produced is high if R is high. The melting point must be low so that wire may melt with increase in temperature
