Electricity and Circuits Review

This is a constant flow of electrons

• electric circuit

• electric current

• electric conductor

• electric insulator

These allow electrons to flow easily through them.

• Electrical insulators

• Electrical conductors

If there is an open circuit path,

• electricity will flow.

• electricity will not flow.

• electricity will flow on and off.

The electrical circuit is the

• motherboard.

• current of the river.

• circular path of electricity.

Electricity will flow if

• there is an open circuit.

• the switch is open.

• there is a closed circuit.

An "on switch" will

• allow electricity to build up.

• make electricity turn off.

• allow electricity to flow.

Materials that do not allow electricity to flow

• are called blockers.

• are called conductors.

• are known as insulators.

"Off switches"

• do not allow electricity to flow.

• do not allow electrons to break out of the nucleus.

Electrons move from

• atom to atom to create heat.

• the nucleus to the shell to create electricity.

• atom to atom to create electricity.

• the nucleus to the proton to create electricity.
