Front

Static Electricity

Back

An accumulation of electrical charges on the surface of an object

Front

Friction

Back

Creates static electricity by transferring electrons between two different surfaces when they are rubbed together

Front

Induction

Back

A redistribution of electric charge in an object that is caused by the influence of nearby charges

Front

Conduction

Back

The transfer of charge between objects that are in direct contact, causing them to acquire the same net charge

Front

Current Electricity

Back

The flow of electrons through a conductor like a copper wire

Front

Alternating Current (AC)
