Question

What is an electric fuse?

Answer 1

Step 1: Definition

An electrical fuse is a low melting point copper or other metal wire that breaks due to heat caused by overvoltage or high load to avoid short circuit or failure to the device.

Step 2: Functions of electric fuses

A fuse is a service that delivers usable electrical circuit over-current safety. Some of the main fuse functions are as follows:

1. Acts as a barrier between both the human body and the electric circuit.
2. Inhibits system failure due to defective operation of circuits.
3. Fuse avoids short-circuits.
4. Inhibits blackouts & overloading.
5. Prevents harm caused by mismatched loads.

Therefore, a fuse is a safety device that protects electrical circuits from the effects of excessive currents.
