One Amp is one Coulomb per second.

a Coulomb, also named after a person.

I chose ions specifically and not electrons because of the flow in the

The Amp is the flow of one Coulomb of charge, equivalent to 6.2 x 10^18
(or
so) elemental charges.
Feel free to check a basic physics text book, I appreciate not everyone

Grow up Brian.

Your attempt to stir things up in order to bandy about insults fails again.

You have failed again because the discussion was that things should not be
named
after people and you slipped on a banana skin with your own mention of the
Coulomb.

Since the Ampere and the second are fundamental units in the SI system,
and the Coulomb is a unit derived from them and therefore is not a
fundamental unit, then one should say that
1 Coulomb = 1 Ampere-second
Read up on 'SI fundamental units'.

(The SI is but one in a number of arbitrary systems of units)

ISTR that the SI system is based upon things that can actually be measured
experimentally and not upon some theoretical bases that cannot be measured.

But how does one fashion a pair of infinitely long parallel wires in order
to be able
to measure an ampere has yet to be revealed :-)

PS 10^18? ISTR 10^19

A meaningless comparison, since ions don't all carry the same amount of
charge.

You seem to be confusing two methods. One based on charge per second
another based on force between conductors. That is the danger of trying
to
impress by using Google.


Grow up, Brian.

Or dear, one of your typical responses when corrected. No wonder you have
failed to improve your knowledge if you always react this way.


Grow up, Brian.

On this occcasion you are mistaken. Currently the Ampere is defined in
terms of magnetic force between infinite parallel conductors, and units
of charge are defived from it. This of course has no effect on the
usefullness of given practical methods of measuring current.

You have jumped in with both feet. I suggest you repeat YOUR Google
research and read what I posted.

You should find nothing I have posted conflicts with your post.

So, despite your unnecessary and rather childish jibe it is YOU who googled,
for
I spoke off the cuff without reference to anything else.

You've been caught with your trousers down, OM.
