Question

3. A fuse (consists) has _________​

Answer 1

A fuse commonly consists of a current-conducting strip or wire of easily fusible metal that melts, and thus interrupts the circuit of which it is a part, whenever that circuit is made to carry a current larger than that for which it is intended. The screw-plug fuse was once commonly used in domestic electrical systems.

Answer 2

A fuse consists of a metal strip or wire fuse element.

Explanation:

• A fuse unit is made up of a metal fuse element or link, a series of contacts to which it is connected, and a body that supports and isolates them. Many fuses contain a mechanism for extinguishing the arc that forms when the fuse element melts.
• A fuse is a safety device that protects electrical gadgets from electric fires and damage caused by excessive current flow. The heating effect of current is used to operate a fuse.
• A fuse is made up of a small piece of tin-plated copper wire with a low melting point. Electrical fuses act as small circuit breakers.
