  • High current means a lot of energy is lost as when current flows the wires heat up and release thermal energy to surroundings.
  • If you increase the Potential Difference you decrease the current.
  • The National Grid uses high PD and low Current to make it efficient with less energy lost.
  • Its cheaper to increase Potential difference.
  • The Step-Up Transformers increase the Potential Difference.
  • The Step-Down Transformers decrease the Potential Difference. To make it safe for consumers to use.
  • The National Grid is a system of cables and transformers where electricity is carried across the UK.
