Q5. The live wire of a 240 V mains supply is protected by a 15A fuse, A 3.0 kW heater is connected to the supply. The arrangement is shown in Fig.5.1.
                 
  (a) Name the wires P, Q and R.
          Fully describe the function of the earth wire.

  (b) The user wishes to connect a 2.0 kW heater in parallel with the 3.0 kW heater shown in Fig.5.2. Discuss, using suitable calculations, whether this would be a sensible idea.
          

(c) The element in the heater is made of metal. Use kinetic theory to describe the effect on the atoms of the metal as the temperature rises.
