Electricity and circuits

The rate of flow of electrons through a conductor

Potential difference between two points in a conductor

Electrical energy needed to move the electric charges from one point to another point in a conductor

Ability of a conductor to resist the flow of electric current

an outlet or switch

a path which an electric current flows

a poor conductor

Wire, battery, and bulb

Battery, switch and wire

Switch, bulb, and battery

Bulb, wire and switch

plastic straw

cotton string

aluminum foil

rubber eraser

wood

brick

copper

plastic

To make it look pretty

To help electricity flow along the wire

To make it safe

To add more energy

Because copper is shiny

Because copper conducts electricity

Because copper is not magnetic

Because copper insulate electricity

A battery that has energy.

Wire that is insulated.

A switch that is open.

Another bulb of the same size.

This circuit will work because it is an open circuit.

This circuit will work because it is a closed circuit.

This circuit will NOT work because it is an open circuit.

This circuit will NOT work because it is a closed circuit.

the electricity will still flow

the electricity will jump over the gap

the electricity will not flow

you will get electrocuted

switch

light

battery

wires

Fuse

Resistor

Heater

Strip light
