Two statements describe the UK mains electricity supply:

  • The potential difference between the live wire and the neutral wire is P P\,P volts.
  • The potential difference between the neutral wire and the earth wire is Q Q\,Q volts.

Which of the following correctly identifies P P\,P and QQQ?

A

P=0P = 0P=0, Q=230Q = 230Q=230

B

P=230P = 230P=230, Q=0Q = 0Q=0

C

P=230P = 230P=230, Q=230Q = 230Q=230

D

P=0P = 0P=0, Q=0Q = 0Q=0
