Question

5. A fuse wire has:
(a) a high resistance (b) low melting point (c) protect the electrical appliances
(d) all the above​

Answer 1

Explanation:

As a high amount of current is passing, resistances of the fuse wire have to be large due to which the heat produced will be high and it is broken down immediately. Hence, fuse wire is a wire of high resistance and low melting point. Hence, option B is correct.
