Question

What are insulators ???
​

Answer 1

Answer:

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. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily. The property that distinguishes an insulator is its resistivity; insulators have higher resistivity than semiconductors or conductors. The most common examples are non-metals.

Hope it helps. :)

Answer 2

Explanation:

Insulators of Light:- the objects which do not allow light to pass through them easily are called insulators.

Insulators of Electricity:- the objects which do not allow electricity to pass through them are called insulator.

Insulators of Heat:- the object which do not allow hi to pass through them are called insulators.
