It depends on what it's made of. A metal is a conductor and a nonmetal is an insulator.
This solid is a semiconductor.
Its a insulator
A seashell is typically considered an insulator because it does not easily conduct electricity. The material of the seashell is not a good conductor of electricity due to its high resistance.
Lead is a metal and is considered a good conductor of electricity. It is not a semiconductor or insulator.
Copper - best conductor Glass - moderate insulator Rubber - good insulator
This solid is a semiconductor.
Brass will conduct both electricity and heat. So brass is a conductor, but not an insulator.
Glass in a molten state is a conductor of electricity. When glass turns to a solid state it becomes an insulator.Basically, glass in a window or a test tube would be the solid state and so it is a insulator of electricity.
insulator.
It is an insulator
Glass in its solid state is an insulator of electricity.

A gas is usually a poor conductor of electricity. In contrast, a brittle solid material that is a poor conductor of electricity is typically an insulator.

Plastic is an electrical and thermal insulator.
