Question

2.
Which of the following allow the electric current to pass through it-
Ans. a) Glasses b) Graphite c) Rubber
d) PVC​

Answer 1

b)Graphite allows the electric current to pass through it.

• We can simply describe graphite as a form of carbon which is crystallized.
• The atoms inside a graphite have electrons which are delocalized. If we look upon the structure of graphite, a carbon atom forms bons with three other carbon atoms adjacent to it. One of the carbon atoms hence remains free for the conduction of electricity.
• These delocalized electrons generate electric current inside graphite.
• Due to the electric conduction properties of these delocalized electrons, graphite is known to be a good conductor of electricity.
• Other options are not correct as electric current cannot pass through glass, rubber or PVC.
