    • What is current?
      The rate of flow of charge
      Measured in amps
    • What is potential difference?
      Difference in electrical potential between 2 points
      Created a 'pressure' that 'drives' current
      Measured in volts
    • What is resistance?
      Opposes flow of current
      Measured in ohms
    • V=IR
      Potential difference= Current × Resistance
    • Q=It
      Charge = Current × Time
