Question

Here a silver string there is a random motion for free electrons why don’t constitute an electric current

Answer 1

Answer:

here is no potential created in the string

Answer 2

In a string made of silver, it is found that the free electrons moves randomly in different direction. But still they are not used for exhibiting the property of conducting electricity.

It is due to the following reasons :

1. Silver is a very costly or expensive metal, so it is not used as a wire.

2. Silver is very malleable and is very soft type, therefore it has chances to get wear and tear.

3. Silver tarnishes very easily, so it does not serve as a very good conductor.
