  16. Coulomb (C)
    The quantity of charge that is equal to the charge of 6.25 x 10^18 electrons.

    Image Upload
  17. Ampere (A)
    The unit of electric current, equal to one coulomb per second. An ammeter is used to measure this value.

    Image Upload
  18. Electrical resistance
    The property of a substance that hinders electric current and converts electrical energy to other forms of energy. Resistors are used to decrease electric current through a component by a specific amount.

    Image Upload
  19. Resistor
    A device used in an electric circuit to decrease the current through a component by a specific amount.

    Image Upload
  20. Load
    A resistor or any other device that transforms electrical energy into heat motion, sound, or light.

    A light bulb is a load that turns electrical energy into light.

  21. Potential Difference (voltage)
    The difference between the electrical energy per unit of charge at two points in a circuit.

    Image Upload
  22. Volt (V)
    The unit of potential difference, equivalent to one joule (J) per coulomb (C).

    i.e. Most cells are listed as having 1.5V of potential difference (even C and D size batteries).
  23. Circuit Diagram
    A diagram that uses standard symbols to represent the components in an electric circuit and their symbols.

    Image Upload
  24. Series Circuit
    A circuit in which there is only one path along which electrons can flow.

    Image Upload
  25. Parallel Circuit
    A circuit in which there is more than one path along which electrons can flow.

  26. Ohm's Law
    The ratio of potential difference to current is a constant called resistance.

    Image Upload
  27. Ohm
    The unit of electrical resistance, equivalent to one volt per ampere (V/A).

  28. Superconductor
    A material through which electric charge can flow with no resistance.

    Image Upload
  29. Non-Ohmic
    Not following Ohm's Law.

  30. Loads in Series
    • - Current is the same throughout the circuit
    • - Potential difference is split evenly through every load and equals the potential difference between the terminals of the cell
    • - Resistance increases as more loads are added to a series circuit

    Image Upload
  31. Loads in Parallel
    • - Potential difference is the same throughout the circuit
    • - The current entering loads that are connected in parallel is equal to the sum of the currents entering all loads
    • - The resistance of loads that are connected in parallel is less than the resistance of the smallest road
