Question

what is conductor? what is insulator. mention with types

Answer 1

Basically, in reality, there is no such things as insulator or conductor.
But, in general and bookish terms,
conductor is anything with low resistence or which allow current to pass through it easily. Ex - copper.
Insulator is anything with high resistance or which doesn't allow current to pass through it easily. Ex- wood.

Answer 2

$\textbf{\large{Answer -}}$

$\textbf{\underline{Conductor :}}$

》Material which permits the electric current or heat to pass through it is known as conductor.

》The potential energy remains same at all point of the conductor.

》Conductors have low resistance.

》Conductors are used for making electrical wires.

》Examples are Irons, aluminum, silver, copper, etc.

$\textbf{\underline{Insulator :}}$

》Materials which restrict the electric current or heat to pass through it is known as insulator.

》The potential energy remains zero in insulator.

》Insulators have high resistance.

》It is used for insulating electrical cable or conductors.

》Examples are rubber, wood, Paper, etc.
