Hi RJ
Actually I do understand what you are saying (at length). I happen to agree with some of it.
Certainly the instruments are not 100% accurate, I merely observe that it strange that they measure resistors accurately but not wires, and that measured resistance changes, if it changes at all, in a matter entirely opposite to what I would have expected. Nothing you have said causes me to doubt the significance of these observations. But then I am a bit thick.
In general I dislike being patronised..." a simple formula", etc. I think I first met that particular formula in 1966 in first year O level physics - yes I am that old. I understood it then and I still understand it, although for how long I do not know...yes I am that old. Did I just repeat myself? How silly.
