  • DC Electricity
    • Definitions
      • Electric Charge - Property of matter upon which the electric force acts.
      • Current - Rate of flow of charge.
      • Potential Difference - The energy transferred per unit of charge.
      • Resistance: Opposition the the flow of current.
      • Resistivity - The amount of resistance given from a unit volume of a substance.
    • Units and Symbols
    • Equations
      • Current: I = Q/T
      • Potential Difference: V=W/Q
      • Resistance: R=V/I
      • Power: P=V/I
    • Ohms Law
      • If the temperature of a metallic conductor and any other physical features stay constant then the current through a wire is proportional to the potential difference across its ends.
        • Straight line graph.
        • Origin is passed through.
    • Circuits
      • Series
        • In series circuits, the resistance adds to give the total resistance.
      • Parallel
        • The resistance will be lower than the lowest resistor.
  • Loop Law
    • Vs = V1 + V2 + V3
    • The total potential    difference of   all the components across the circuit equals the total input of the voltage in the cell.
      • Vs = V1 + V2 + V3
