Explanation
The question refers to the mains electricity supply in the UK, which has specific standard values for potential difference (voltage) and frequency. The potential difference is the voltage across the power supply, and the frequency of change of the electric current in Alternating Current (AC) supply, in terms of cycles per second or Hertz (Hz).
