   How does the National Grid work in the UK?

   • In the UK the National Grid connects all the generators of electricity, like power stations, to all the users, for example homes and offices. Mains electricity is an alternating current (a.c) which means that the current keeps changing direction. Current from batteries is direct current (d.c) meaning it always flows in the same direction.

   Why does the National Grid use a high potential difference?

   • The National Grid transfers electricity using a high potential difference and a low current . This is because the National Grid needs to transfer a very large amount of energy. A high current cannot be used because the wires would get very hot and a lot of energy would be lost to the surroundings as heat energy .

   How does electricity move around the National Grid?

   • To move power around the National Grid: The transfer of electrical energy via the grid is very efficient. When currents in a cable are higher, more energy is to the surroundings through heating. As high currents waste more energy than low currents, electrical power is transported around the grid at a high voltage and a low current.
