circuit

A circuit is a pathway through which electric current flows.

A closed circuit allows electricity to flow; an open circuit

does not.

Conductors are materials that allow the flow of

electricity.

Insulators are materials that do not allow the flow of

electricity.

A switch is a device that opens and closes a circuit.

Circuit base

component is any part of a circuit system (wires, D-cell, bulbs).

A bulb is an energy receiver that produces light.

D-cell is a source of electric energy.

To make a complete circuit, electricity must travel in a circle from the negative end of the battery, through the

circuit, and to the positive end.

A Motor is an energy receiver that produces motion.

All Metals are conductors.

Metals that are covered with an insulating layer will not conduct electricity.
