Question

on what principle an electric fuse works?

Answer 1

An electric fuse works on the principle of $\bf{Heating\:effect\:of\:electric\:current}$

A fuse is a safety device that has a wire made up of copper or that has low melting point like tin, zinc,etc.

The fuse wire is directly connected to the live wire. When the current exceeds its normal value, the wire gets heated up and having low melting point, they melt and break the circuit.

In this way all the devices connected are safe from loss.

Nowadays $\bf{Miniature\:circuit\:Breakers\: (MCBs)}$ are used that work on the principle of $\bf{Magnetic\:effect\:of\:electric\:current}$.
Unlike heating up of wire, they have electromagnets that put down the MCBs automatically disturbing the flow of current.

Answer 2

Hey dear!!

here is your answer:

✔A fuse is a device which works on the $\bf{heating effect}$ of electric current!

• It has a thin wire in between with a very low melting point.

• If a large amount of electricity flows through the electric fuse.....the wire in between melts and breaks the circuit eventually......

• This helps to prevent short circuit in the system.......coz the circuit breaks before the current reaches the system.....

--------------------------------------------------
✔The main use of an electric fuse is that it prevents a sudden, large amount of electricity to flow through the circuit eventually.........

✔ Nowadays, electric fuse are being replaced by MCB (Miniature Circuit Breaker)

✔The MCB works on the Magnetic effect of current.
