OK, job done, now that it seems I have successfully got a few of you at each
others throats, I'll just back out now and disappear into the
sunset.........No, joking of course. Hey look, of all the explanations and
analogies etc I have to work with I do believe I'm building up a picture of
how 'things' actually work here. Jeez, if nothing else it certainly has
prompted some conversation! I hope you show similar patience and tolerance
to the next duma$$ who may decide poke his nose in here.....he will probably
need to be sitting back aways from the computer screen just out of reach I
suspect! <rather large g>
No, this has been very good, I will continue to go through all that yous'
have said. I am starting to get a picture of how it works and am even
beginning to understand voltage, current etc and terminologies.

This, I am going to look at a little more closely. In my language again, I
could say...electrons 'flow' one way but current flows in the opposite
direction, or perhaps...the positive could be thought of as a 'magnet'
maybe, pulling the electrons to the negative while the electrical 'flow' of
current actually goes the opposite way...yes?.............hang on a minute,
stop there!...is this the 'gliding' thing someone spoke of? current flows
in a particular direction which causes electrons to 'slide', 'glide', 'slip'
past and be 'forced' if you like, the opposite way......wait for
it.......due to the voltage, ie; 'pressure' being applied to those same
'electrons'...yes? So if one is talking about 'current', then that will go
one way but if one is talking about 'electrons' then they will go the
opposite way, which is why it's hard to get a definitive answer about
'direction' unless it is specified what one is talking about...ie; current
or flow!
I eagerly await a reply to this one!
Neville.

Didit; but other than that small glitch it was an excellent explanation
for Neville's purposes, Props!!
