Question

Defination of conductor,insulator and semiconductor

Answer 1

_the the substances which can conduct electricity due to the motion of free electrons are called as conductors.
the conductivity decreases with increase in temperature
_ insulators are the substances which cannot conduct electricity.
_do substances whose conductivity are in between conductors and insulators and semiconductors their conductivity increases with increase in temperature due to P type and n type substances

Answer 2

Hey !!

Question = Definition of conductor,insulator and semiconductor ?

Answer

CODUCTOR :- The solids with condcutivities ranging between 10⁴ to 10⁷ohm⁻¹ m⁻¹ are known as Conductors. Metals have conductivities in the order of 10⁶ to 10⁷ ohm⁻¹m⁻¹. They are Good conductors.

INSULATOR :- As we know insulators are very poor conductors of electricity. They are the solids with very low conductivities ranging between 10⁻²⁰ to 10⁻¹⁰ ohm⁻¹m⁻¹. Diamond is the best familiar insulator.

SEMICONDUCTOR :- The solids with intermediate conductivity ranging between 10⁻⁶ to 10⁴ ohm⁻¹m⁻¹ are called semiconductors.
