Does the plus in voltage source symbol represent the highest potential end or does it represent the positive end?
Is that answer true for IEEE and IEC and NEC?
It may seem trivial for those who know but I did my research and did not find the answer.
My question arises due to the fact that there is electron flow (the real one when electrons are the charge carriers) and convention flow (the adapted one to avoid thinking "negatively" twice).
If the plus means the positive end, then electrons are moving into that end in electron flow, since electrons will go from the negative end to the positive one.
If the plus means the highest potential end, then electrons are moving out of that end in electron flow, since electrons will go from high potential to low potential.
