Conductor

Back

A material that allows the flow of electric charge, typically metals like copper and aluminum.

Front

Insulator

Back

A material that resists the flow of electric charge, such as rubber, glass, or plastic.

Front

Conduction

Back

The process by which electricity is directly transmitted through a substance when there is a difference of temperature or electrical potential.

Front

Induction

Back

The production of an electric or magnetic effect through the influence of a nearby electric or magnetic field without direct contact.

Front

Friction

Back

The resistance that one surface or object encounters when moving over another, often causing static electricity.
