Practice question

At input P of a solar inverter, the potential difference is 21 V and acts in one direction only. At output Q, it repeatedly reverses direction, has a frequency of 50 Hz and a value of 232 V. Determine the type of potential difference at P and Q. Decide whether Q is consistent with UK domestic electricity, explaining each decision.

Which answer would score higher?
