Answer 2

The material which do not allow electric current to pass through it is known as

(A) Electric conductor

(B) Insulator

(C) Electric resistance

(D) Semi conductor

Answer : option (B)

• Insulators are such materials that do no allow electric current to pass through them . This is because they have a very low value of conductivity and a comparatively high value of resistivity . The forbidden gap is greater than 3eV. Thus, they don't conduct electricity.

• It includes materials like paper , wood , glass etc.
