  • Electricity in the home
    • AC/DC
      • Direct current flows in one direction
      • Alternating current repeatedly reverses its direction of flow
      • Mains current has a live wire which is AC
      • Peak potential difference of an AC supply is the maximum voltage when measured from 0 volts
      • AC Frequency = 1 / time taken for 1 cycle
    • Cables and plugs
      • Live Wire (brown)
      • Earth Wire (green and yellow)
        • longest pin
        • earths the metal case of a mains appliance
