As I mentioned before, for the purpose calculation or demonstration it makes absolutely difference if R7 is 10Ω in one leg or 5Ω in both legs. Further, at 50Hz the final results are unlikely to be incorrect either.

It doesn't, but it can be argued that if one is going to model something for demo purposes, one might as well model the actual situation, rather that something that is 'equivalent' to it.
Do you mean "correct" (rather than "incorrect")?
If, as has been implied, the 'resistors' all represent resistive elements, then I don't see why the answers should be any different with AC of any frequency - but, in any event, I don't think that is relevant to the exercise, is it?

That would depend on the design/type of the resistors.
Hmmm - did you not read the first part of my sentence which you omitted in your quote of me, which said ..
Do I take it that you are trying to be 'clever' by invoking resistors which do NOT "all represent resistive elements"?

Wire-wound resistors?
Quite - which is why I made it clear (or thought I had) that I was talking about resistors which were 'purely resistive' - i.e. not wire wound.
In any event, I very much doubt that you would easily find a wirewound resistor which had a significance reactance at 50Hz! - the usually have a small number of turns of relatively high resistance wire, hence very little inductance.
