Electric circuit
 An electric circuit is a path that allows electrons to freely flow through it.

Voltaic cell
 A voltaic cell is a cell that generates charge through the chemical reaction of two pieces of metal,with a conducting liquid separating them.

Battery
 A battery is a group of two or more cells,that generates charge through chemical reactions.

Electrode
An electrode is a metal strip that reacts with the electrolyte in the cell.

Electrolyte
 An electrolyte is a paste or liquid or paste that conducts electricity.
 e.g. alkaline.

Dry cell
 A dry cell is a cell that does not have liquid as the electrolyte, the electrolyte is generally a paste.
 e.g. a battery

Wet cell
 A wet cell is a cell that has a liquid electrolyte to help generate electricity.
 e.g. Car battery

Primary cell
 A primary cell is a cell that can only be used once/disposable.
 e.g. alkaline battery.

Secondary cell
 A secondary cell is a cell that can be used more than once/rechargable.
 e.g. a cell phone battery.

Fuel cell
 A fuel cell is a cell that has its fuel stored outside of it.
 e.g. Hydrogen fuel cell

Solar cell
 A solar cell is a cell that converts solar energy into electric energy.
 e.g. solar panels

Terminal
A terminal is a device that connects a electrical devices to external circuits.

Switch
 A switch is a device that can control if a circuit is closed or open.
 e.g. light switch

Open circuit
A open circuit is a circuit that is not closed therefore electrons can not completely flow through it.

Electrical current
The amount of current that passes by a point in a circuit in a second.

Coulumb
A coulomb is a unit of charge that is equal to 6.25 × 10 18 electrons.

Ampere
An ampere is the measure of the amount of current passing by a certain point in a circuit in a second.

Electrical resistance
 Electrical resistance is the difficulty that electrons have to pass by measured in ohms
 R=V÷I

Resistor
 Any material that slows down the flow of electrons.
 e.g. light bulb filament

Load
A load is a device that converts electric energy into another type of energy.

Potential difference
The potential energy difference between two points in a circuit.

Volt
The measurement for potential difference.

Circuit diagram
 A circuit diagram is a diagram that simplify s how a circuit works and shows all of the components in a normal circuit.

Series circuit
 A series circuit is a circuit that has only one path for the electrons to flow through.

Parallel circuit
 A parallel circuit is a circuit that has more than one path for electricity to flow through.

Ohms law
The law that says as long as temp. stays the same V=IR

Ohm
A ohm is a unit to measure the resistance in a circuit.

Superconductor
 A superconductor is a conductor with no or minuscule resistance.
 e.g. hadron collider

Nonohmic
 A circuit or material that does not obey ohm's law.
 e.g. LED

Loads in series
Loads in series are in a straight line and share the same energy, they also have to share a fraction of the current.

Loads in parallel
Loads in parallel all get the same amount of potential difference that the power source produces.
