Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows the flow of electric current or heat through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current or heat. Examples include rubber, glass, and plastic.

Why is plastic considered a poor conductor of heat?

Back

Plastic is considered a poor conductor of heat because it has a high resistance to heat flow, making it an effective insulator.

Front

What is the primary difference between conductors and insulators?

Back

The primary difference is that conductors allow the flow of electricity or heat, while insulators resist it.
