When an atom gains or loses electrons When an atom gains or loses electrons. A positively or negatively charged atom.

Ion

Positively Charged Ion

Electric charges flowing continuously through a closed conducting loop.

Circuit

Negatively Charged Ion

The flow of electric charge.

Electric Current

How much electric potential energy an electron can gain.

Voltage

Complete Circuit

A rapid movement of electric charge from one place to another A rapid movement of electric charge from one place to another. An example of this is lightning

Electric Discharge

A material in which electrons can not move easily from place to place.

Insulator

A circuit that has more than one path for the electric current to follow.

Parallel Circuit

A material that allows electrons to move easily through it.

Conductor

The measure of how difficult it is for electrons to flow through a material.

Resistance

The process of providing a pathway to drain excess energy into Earth.

Grounding

A circuit that has only one path for the electric current to follow.
