What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of an object, which can result from friction.

What is the principle of conservation of charge?

Back

The principle of conservation of charge states that the total electric charge in an isolated system remains constant.

What is an insulator?

Back

An insulator is a material that does not allow electric charges to flow freely, such as rubber or glass.

What is a conductor?

Back

A conductor is a material that allows electric charges to flow freely, such as copper or aluminum.
