  1. Electric circuit
    • An electric circuit is a path that allows electrons to freely flow through it.
  2. 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.
  3. Battery
    • A battery is a group of two or more cells,that generates charge through chemical reactions.
  4. Electrode
    An electrode is a metal strip that reacts with the electrolyte in the cell.
  5. Electrolyte
    • An electrolyte is a paste or liquid or paste that conducts electricity.
    • e.g. alkaline.
  6. 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
  7. Wet cell
    • A wet cell is a cell that has a liquid electrolyte to help generate electricity.
    • e.g. Car battery
  8. Primary cell
    • A primary cell is a cell that can only be used once/disposable.
    • e.g. alkaline battery.
  9. Secondary cell
    • A secondary cell is a cell that can be used more than once/rechargable.
    • e.g. a cell phone battery.
  10. Fuel cell
    • A  fuel cell is a cell that has its fuel stored outside of it.
    • e.g. Hydrogen fuel cell
  11. Solar cell
    • A solar cell is a cell that converts solar energy into electric energy.
    • e.g. solar panels
  12. Terminal
    A terminal is a device that connects a electrical devices to external circuits.
  13. Switch
    • A switch is a device that can control if a circuit is closed or open.
    • e.g. light switch
  14. Open circuit
    A open circuit is a circuit that is not closed therefore electrons can not completely flow through it.
  15. Electrical current
    The amount of current that passes by a point in  a circuit in a second.
  16. Coulumb
    A coulomb is a unit of charge that is equal to 6.25 × 10 18 electrons.
  17. Ampere
    An ampere is the measure of the amount of current passing by a certain point in a circuit in a second.
  18. Electrical resistance
    • Electrical resistance is the difficulty that electrons have to pass by measured in ohms
    • R=V÷I
  19. Resistor
    • Any material that slows down the flow of electrons.
    • e.g. light bulb filament
  20. Load
    A load is a device that converts electric energy into another type of energy.
  21. Potential difference
    The potential energy difference between two points in a circuit.
  22. Volt
    The measurement for potential difference.
  23. 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.
  24. Series circuit
    • A series circuit is a circuit that has only one path for the electrons to flow through.
  25. Parallel circuit
    • A parallel circuit is a circuit that has more than one path for electricity to flow through.
  26. Ohms law
    The law that says as long as temp. stays the same V=IR
  27. Ohm
    A ohm is a unit to measure the resistance in a circuit.
  28. Superconductor
    • A superconductor is a conductor with no or minuscule resistance.
    • e.g. hadron collider
  29. Non-ohmic
    • A circuit or material that does not obey ohm's law.
    • e.g. LED
  30. 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.
  31. Loads in parallel
    Loads in parallel all get the same amount of potential difference that the power source produces.
