Why are Amps a base units instead of Coulombs? It wouldn't change the math at all either, and it would makes things more rigorous. It's an overall positive gain.
Someone should message the scientists, this needs to be changed.

Charge Flow Rate (Coulomb/s)= Amp

How does changing the word from 'Amps' to 'coulombs per second' translate into stronger rigor? That's just an issue of nomenclature, not rigor.

I agree with you, just imagine that we still use the garbage "conventianl flow" in circuit theory... its so wierd that "we have to" live with outdated/non consistent models... even when we know they are not correct! just ugly... education should be much more capable to be consistent.

It's because current (Amps) was discovered before charge (Coulomb)

E&M is full of autism like this with the derived units, though, making it impossible to remember any of the units without a reference guide. Amps, Farads, Teslas...

>>10694319
Electrons aren't the only charge carriers possible. Also, keeping track of the sign of voltage is easier this way since we don't have a bunch of negatives. Same as multiplying both sides of an equation by -1 though

>using either amperes or coulombs
The basic unit of charge should be exactly 10^18 electrons, prove me wrong faggots

thats the point tho, it doesn't matter the timeline because our methods should be rigorous.. models should be updated in a logical way when things advance like in this case where coulomb/s represent much better what is happening , your point only proves that all this is just ego "we want to give recognition to all this people even if the model gets inconsistent"

heres another example of not making the effort to keep a logical model this time in DNA studies:

"...in 1983 we had a very logical nomenclature but later a lot of people jump in and now we have different names and they don't necessarily make any sense..."

if you're going to get angry about base units, get angry the base unit is kilogram, not gram

but setting coulomb's to be the base unit and deriving amperes isn't any more rigorous than how SI currently works

>> No.10695432

>>10693450
Charge is quantized, so measurements have immediate finite precision. Since velocity is not quantized (at least not on as large a scale as charge) it makes more sense to measure what can be found with higher precision.

Also, it is easier to build an accurate amp-meter than an accurate charge-meter.

>> No.10697436

>>10695432
amp is derived from coulomb so by it self it mutes your point, and coulomb actually can give you directly what could be considered absolute precision in electrical measurement= one electron per second... what OP is claiming is to use directly coulomb instead of using a "secong layer" unit if I can called it that way.

>"The earlier CGS measurement system had two different definitions of current, one essentially the same as the SI's and the other using electric charge as the base unit, with the unit of charge defined by measuring the force between two charged metal plates. The ampere was then defined as one coulomb of charge per second.[6] In SI, the unit of charge, the coulomb, is defined as the charge carried by one ampere during one second. "

It literally doesnt matter. Physics units are entitely arbitrary. If you want to be entirely objective and perfect, you can write things down using Planck Units.
