hello the current goes from negative to positive but the conventional to negative rule is used but that Does it not affect an eo circuit in some other way?

To understand it better, you have to analyze an atom, which in its nucleus are protons (positive charge) neutrons (neutral charge) electrons (negative charge) surround the nucleus of the atom, these by means of an applied force depends on the material, they can be yielded to another more or less easily. In short, what has movement to say when applying an energy (electric, heat, light, etc.), are the electrons of negative charge.

Both directions of the current are correct. The electronic sense is from negative to positive, since the current is the movement of electrons and they have a negative charge. But as you can not see, the conventional system was created that says that the current flows from where there is the greatest amount of charges (+) to where there is the least amount of charges (-) other than the circulation of the current from positive to negative . The same goes for the pressure; temperature; water level etc., which in all tends to produce balance. Since the electronic diagrams are designed in the conventional system, you must keep it in mind. Try to follow the feeding of any electronic diagram starting from the negative to the positive and then starting from the positive to the negative and tell which one is the most practical. Regards
