      • Heater
    • Current
      • Charge flow = Current X Time taken
      • Electric current is a flow of charge.
    • Potential Difference
      • Potential difference is a measure of the energy transferred to the lamp by each coulomb that passes through it.
      • potential difference = resistance X current
      • the unit of P.D is volts
    • Resistance
      • resistance = p.d / current
      • the unit of resistance is Ohms
      • Temperature, length and thickness all effect resistance.
