The ampere is far easier to measure with precision than is the coulomb.just
The second is easy to measure. Therefor, the ampere and second are
measured, and the coulomb is derived.
I say, on the contrary. Coulmbs are "fundamental," while amperes are
a convenient simplification of the concept "coulombs per sec." And,while
this violates the concept "fundamental vs derived" it is more correctthan
the reverse, and I believe that it makes much more sense to the
inexperienced learner.
Now, how does one convince a textbook publisher to take this idea
seriously, when he/she can open a physics book and find statements saying
"amperes are the fundamental unit."
