Why does the current in the circuit flow from positive to negative?

Why does the current in the circuit flow from positive to negative? and who is behind it? I have such a problem, help me

Actually, it flows from minus to plus! But contractually it is as you wrote.
The current flows from negative to positive, because the current is electrons and the electrons have a negative charge, so they accumulate in the "minus". For the current to flow, there must be a potential difference, and such a difference is in a closed circuit and electrons from where there are more of them flow there where there are fewer of them, which is a plus.

I think I remember well from school What?

it is a matter of a generally accepted contract, but in reality it can be different depending on what is the carrier of the (negative, positive) electric charge.
In conductors, the charge carriers are negatively charged electrons and their real direction is opposite to that assumed as positive.
In electrolytes where ions move, this direction is both ways: positive cations go to the negative cathode, and negatively charged anions go to the positive anode.
In semiconductors, this charge movement is even more complicated, so let me give you a description of it.

greetings

and I found this on one of the pages what do you think about it?
"flows from plus to minus (i.e. from higher to lower potential). Well, it is absolutely true, this is how the direction of the electric current (opposite to the movement of electrons) was assumed! electrons move in the opposite direction. "Oh, and you don't know who came up with this proposition ??

The current flows from plus to minus because historically an elementary charge has been defined as the value of the charge carried by a proton or the absolute value of the charge of an electron. In college, we were taught that the current flows from plus to minus because electrons move from minus to plus one by one, leaving behind empty spaces (in a positively charged crystal lattice, in which something like electrons are floating in the energy conduction band - I think that's good I wrote). Such open spaces are called electron holes, and since their charge is not balanced by any electrons (like an electron hole - there is no electron there), it has a positive charge. Such a free space is replaced by another electron, which leaves behind a free space for another electron to enter etc ... and so the electrons move like cars in a line, and the gaps between them are taken by subsequent cars coming from the back, so such a break gives the impression that it is moving to the back of the queue. phew! That is why the current flows from positive to negative. Or as a colleague wrote above about ions. Greetings.

ok thanks for your help

As far as I know, the current flows from plus to minus and the voltage from minus to plus.
The direction of the current is historically accepted, but the voltage has already been "improved".
