Question

why the electric current doesn't flow through rubber if it is a insulator then what is present in it ​

Answer 1

ANSWER :-

• Rubber is an insulators.Insulators dont allaw current to pass through them.

• In a conductor, electric current can flow freely, in an insulator it cannot.

• They  have  extremely high resistance to the flow of charge through them.

• "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators.

• However, rubber can be loaded with conductive particles, such as carbon and metal microwires. If the loading is high enough, the rubber can become a poor conductor.

Answer 2

An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.
