Plastic

This part of a circuit is what powers the entire thing.

This device converts mechanical energy (gasoline) to electrical energy.

Iron

These are materials in which electrical charge moves easily.

Gold

This part of a circuit allows the electrical flow to powered on and off.

This is the rate at which charge is flowing, and is measured in amps.

Bismuth

These are materials that DO NOT let electrical charge move easily.

Copper

This piece of a circuit is a small piece of metal if current becomes too high, opening the circuit.

This is the difference in charge between two points.

Wood

These are the units that resistance is measured in.

Glass

If you open your phones back open you will see many of these componets.

This is a measure of the opposition to current flow in an electrical circuit

Air

These are the units that voltage is measured in.

Bronze

This part of a circuit converts electrical energy to mechanical energy.

These materials conduct electricity BUT only under certain circumstances.

Pencil lead

These are the units that current is measured in.
