Question 18

Two statements describe the UK mains electricity supply:

  • The peak potential difference between the live wire and the neutral wire is VpeakV_{\text{peak}}Vpeak​.
  • The potential difference between the neutral wire and the earth wire is VNEV_{\text{NE}}VNE​.

Which of the following correctly identifies the values of VpeakV_{\text{peak}}Vpeak​ and VNEV_{\text{NE}}VNE​?

A

Vpeak=230 VV_{\text{peak}} = 230\text{ V}Vpeak​=230 V, VNE=0 VV_{\text{NE}} = 0\text{ V}VNE​=0 V

B

Vpeak=325 VV_{\text{peak}} = 325\text{ V}Vpeak​=325 V, VNE=0 VV_{\text{NE}} = 0\text{ V}VNE​=0 V

C

Vpeak=325 VV_{\text{peak}} = 325\text{ V}Vpeak​=325 V, VNE=230 VV_{\text{NE}} = 230\text{ V}VNE​=230 V

D

Vpeak=460 VV_{\text{peak}} = 460\text{ V}Vpeak​=460 V, VNE=0 VV_{\text{NE}} = 0\text{ V}VNE​=0 V
