Question

An electric fuse works on the ____________ effect of current.

• A. heating
• B. magnetic
• C. chemical
• D. none of these

Answer 1

The correct option is A

heating

Explanation for the correct answer:

1. An electric fuse is a device used in an electrical circuit to avoid overloading or short-circuiting.
2. An electric fuse usually consists of a small metal wire or strip that melts when a high current flows through it.
3. As soon as the current through the fuse wire increases, heat increases and it results in the breaking of the circuit avoiding the damage to the electrical appliances.
4. Since, a fuse uses electrical energy which produces heat and thus, uses the heating effect of electric current.

Hence, option A is the correct answer.
