Question

How to fail the torch light filament and which the chemical used on copper?

Answer 1

Hi,

In order to fail light filament, the chemical used on copper is tungsten.

If the tungsten put in contact with copper, a chemical reaction is likely to cause copper filament to fail.

This will the cause the torch not to function.

I hope that this information will be very helpful to you.

Answer 2

Answer:

• 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.
