An oscilloscope is used to display the waveform of the standard domestic mains electricity supply in the UK, as shown in the diagram.

Mains supply alternating voltage waveform

What are the values of the peak-to-peak voltage Vp-pV_{\text{p-p}}Vp-p​ and the time period T T\,T of this supply?

Vp-p=325 VV_{\text{p-p}} = 325\text{ V}Vp-p​=325 V, T=20 msT = 20\text{ ms}T=20 ms

Vp-p=650 VV_{\text{p-p}} = 650\text{ V}Vp-p​=650 V, T=20 msT = 20\text{ ms}T=20 ms

Vp-p=650 VV_{\text{p-p}} = 650\text{ V}Vp-p​=650 V, T=50 msT = 50\text{ ms}T=50 ms

Vp-p=460 VV_{\text{p-p}} = 460\text{ V}Vp-p​=460 V, T=20 msT = 20\text{ ms}T=20 ms
