That's obviously true, but it probably doesn't matter to the OP - not the least because, in the context we're discussing (loop impedances) impedance and resistance will usually be very nearly identical.Loop impedance is the AC equivalent of loop resistance. So first look at the resistance of a circuit.
Only an idiot would write/publish an idiot's guide on such a subject.Has anyone written an idiot's guide to things like "Z" (?) loop impedance etc? I have no intention of doing any paid work, I just want to understand what the experts here are saying.
If one wants to learn about electrical matters in general, I would obviously agree.So still say start with DC then move to AC.
I doubt that you have forgotten anything. I did A-Level (and 'S-Level', which then existed) Physics in 1966 and am pretty certain that it didn't cover much of the sort of things we've been discussing here.Thanks all .Pleased to see this comes after A level Physics as I passed A Level Physics with an A grade back in 1971 and it didn't cover anything like this. Or maybe it did and I've forgotten!
