Why we still label circuits based upon “conventional” current when we know that current actually flows in the opposite direction?
Pretty much, everything was defined before the discovery of, say the electron. Scientists, being positively minded and optimistic, decided it would probably be the positive charge moving around. Note also how stuff like Capacitance is measured in Farads, which is a huge unit and you usually use m…
The Short Answer
Pretty much, everything was defined before the discovery of, say the electron. Scientists, being positively minded and optimistic, decided it would probably be the positive charge moving around. Note also how stuff like Capacitance is measured in Farads, which is a huge unit and you usually use micro or nano farads because the SI standards are way off. Same with Coulombs. It was defined before that notion of electron charge. So, like Farads, it is also really small. (x10^-16) So yeah, it was just guess work that got well known to the point where it can't be changed, so everybody gets to deal with it.
