Answer 1

Answer:

The chemical effect of tungsten is responsible for this.

Explanation:

In case of a torch light the filament it that is used is made up of a metal name tungsten which gives out light in the form of energy.

When current passes through it the filament of this coil of tungsten is made up of copper.

Hence when a Torchlight fails the actual reason is the reaction of tungsten and copper which makes the copper wire to wear off after reaction and fall off.

Since the contact brakes fails to work the torchlight lights up.
