Electricity

• charge flow equation

  • charge flow = current x time
• the greater the resistance...

  • the smaller the current
• potential difference equation

  • pd = current x resistance
• which wire can give you an electric shock

  • live
• neutral wire

  • completes the circuit
• live wire

  • provides alternating potential difference
• earth wire

  • protects the wiring and for safety
• energy transferred equation

  • energy transferred = charge flow x potential difference
• power equation

  • power = potential difference x current
