Question

Define Insulators . Give two examples

Answer 1

Answer:

Examples of conductors include metals, aqueous solutions of salts (i.e., ionic compounds dissolved in water), graphite, and the human body. Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.

Answer 2

Answer

• Insulators are materials that hinder the free flow of electrons from one particle of the element to another. 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. The common process of charging of such elements includes charging by rubbing (for some elements, with the help of suitable materials) and charging by induction.

Examples of insulators

• Some of the common insulator examples are given below:

1. Plastic
2. Wood
3. Glass
