Ampere-second. The ampere is a fundamental unit, like meters and
seconds.
You didn't know that, I take it.


========================================
Oh my...
The ampere is coulombs/second, a ratio.
The coulomb is the fundamental unit, a capacitor can hold
it's charge independent of time. Some computer memory chips
depend on it.
Phuckwit Duck doesn't know that.

Try again. You can check NIST if you like.

=========================================
Oh my...
" In principle, the coulomb could be defined in terms of the charge of an
electron or elementary charge... A coulomb is then equal to exactly 6.241
509 629 152 65E+18 elementary charges. "
http://en.wikipedia.org/wiki/Coulomb
Note: No seconds needed.

By your illogic velocity is a fundamental unit, like amperes and
seconds.
But you would know that, I take it. I'm glad I don't know what
you know or I'd be calling myself a fuckin' imbecile.

Try again, a capacitor proves Phuckwit Duck WRONG.

The Ampere is the fundamental unit in SI, the Coulomb is derived from it.

See http://physics.nist.gov/cuu/Units/units.html

In different systems, that is not the case .. eg in Planck units, charge is
a basic unit.

So it really is pretty much an arbitrary (but hopefully sensible) choice of
the system to decide which units are basic and which derived.

That's true.
