Strange things have happened! I sent in a replying post to Mark's previous post, which I confirmed was 'there', by a subsequent inspection of 'Today's Posts'. I now find that that post of mine has disappeared! 
I suppose such things will happen from time to time. 
Anyway, I'll try again . . .
Thanks Mark: all of that now clearly understood. One remaining question, if you can advise, please.
I think we've all met the case of the high-ohmic value carbon composition resistor (1 MΩ, say) in an old item of equipment and upon measurement, we find that that 1 MΩ resistor reads something like 5 MΩ. Is such a significant change in the ohmic value caused - or accelerated - by excessive voltage?
