Help, why can`t you use Zs - Ze to accurately determine the value of R1 and R2

[QUOTE="ADS, post: 146866, member: 7231"] Hi mate, [B]Z[/B] is the [B]'impedance[/B]' of the conductors in an AC circuit and is reliant on a number of factors. (measured live) [B]R[/B] is the [B]resistance[/B] of a conductor - (normally a DC measurement whilst circuit is dead) If you google '[B]impedance'[/B] you will immediately realise the difference between the two. :) It therefore stands to reason that if you take one 'impedance' ([B]Ze[/B]) from another 'impedance' ([B]Zs[/B]), your answer cannot possibly be a 'resistance' ([B]R1+R2[/B]) :D Your answer will be another Z or 'impedance' - the difference between Zs and Ze.
