Question

A substance that does not allow an electric current to pass through it is called_________

Answer 1

1. Insulators are materials that hinder the free flow of electrons from one particle of the element to another.
2. If we transfer some amount of charge to such an element at any point, the charge remains at the initial location and does not get distributed across the surface.
3. The most common process of charging of such elements is charging by rubbing (for some elements, with the help of suitable materials).
4. Examples of insulators are wood, glass, plastic, etc.
