  1. Electric Circuit
    A closed path along which electrons that are powered by an energy source such as a battery can flow.
  2. Voltaic Cell
    A cell of energy that generates an electric current by chemical reactions involving two different metals or metal compounds separated by a solution that is a conductor.
  3. Battery
    A connection of cells.

    E.G 2 cells connected are 3 V
  4. Electrode
    1 of 2 terminals in a cell
  5. Electrolyte
    • A liquid that contains ions which can be
    • decomposed by electrolysis.

    e.g. Present in a battery.
  6. Dry Cell
    An electric cell in which the electrolyte is absorbed in a solid to form a paste, preventing spillage.
  7. Wet Cell
    An electric cell where the electrolyte is a liquid.

    E.G Car battery
  8. Primary Cell
    An electric cell that produces current by an irreversible chemical reaction.
  9. Secondary Cell
    A cell that can be recharged.
  10. Fuel Cell
    A cell producing an electric current directly from a chemical reaction.
  11. Solar Cell
    A device that converts solar radiation into electricity.
  12. Terminal
    A point of connection for closing an electric circuit. 

    E.G Terminals of a battery
  13. Switch
    A device for opening and breaking the connection in an electric circuit.
  14. Open Circuit
    An electric circuit where the current isn't flowing.
  15. Electric current
    The flow of electricity through a conductor.
  16. Coulomb
    The SI unit of electric charge.  It is equal to the charge of approximately 6.241×10^18 electrons
  17. Ampere
    A unit of electric current which is equal to a flow of one coulomb per second
  18. Electrical resistance
    A material's opposition to the flow of electric current which is measured using ohms.
  19. Resistor
    A device having resistance to the passage of an electric current.
  20. Load
    A device or the resistance of a device to which power is delivered.
  21. Potential difference
    • The difference of electrical potential between
    • two points.

    E.G The potential difference of a cell is usually 1.5 V
  22. Volt
    The SI derived unit for electric potential difference.
  23. Circuit diagram
    A simplified graphicalrepresentation of an electrical circuit.
  24. Series circuit
    A circuit which has its parts connected in series.
  25. Parallel Circuit
    A closed circuit in which the current divides into two or more paths before recombining to complete the circuit
  26. Ohm’s
    law
    • A law stating that electric current is
    • proportional to voltage and inversely proportional to resistance.

    E.G V = IR
  27. Ohm
    The SI unit of electrical resistance,transmitting a current of one ampere when subjected to a potential differenceof one volt.
  28. Superconductor
    A conductor with no electrical resistance when cooled to a certain point.

    E.G. Mercury
  29. Non-Ohmic
    Resistors have changing ratios, and are defined by their instantaneous resistance
  30. Loads in Series
    Loads which are connected in a series connection.
  31. Loads In Parallel
    Loads which are connected in a parallel connection.
