So,

Let the question is

Q. Which device is used to prevent from overload?

Ans. Fuse wire is used to prevent from overload of electrical circuits in homes,offices and factories.

It has low melting point,whenever load increases in the circuit,fuse wire melts,so as the circuit breaks and no loss encounter to electrical appliances.

Composition of fuse wire:

Fuse wire is composed of tin (Sn) and lead (Pb)

these have high resistance and low melting point.

Now a days MCB's are used at the place of fuse wire,because of its high reliability.

Full form of MCB is Miniature Circuit Breaker.

Along with prevention of circuit from overload it also distribute equal power among all electrical appliances.
