Current Direction

what is Current Direction?

when electrons move in a wire from side to side this creates a current direction.

we know that the atoms of anybody are always in equivalent state, Whereas number of protons (positive charge) is equal to the number of electrons(negative energy) around the nucleus, when a body loses some electrons from their atoms, it becomes a positive charge ,& the body which Acquires more electrons becomes a negative charge.

now when we close an electronic circuit, current flows in it and that means there is a flowing of electronic charges in that electronic circuit, and These charges move from one of the battery poles through these wires going through the circuit elements and finally reach the other pole of the battery.

Traditional Direction :

in the past before founding electronics, a lot of scientists who have studied electricity

that electric current is a mobile electrical charge and then they assumed that the electric current is the flow of charges in an electric circuit which is outside the battery, from positive pole to the negative pole and we call it Trend of conventional current.

Real Direction:

the real direction of the current is the direction of electrons from negative to positive

, After we have known the electrons the definition of electric current has been changed which is [electric current is the flow of negative electric charge in an electric circuit, and this charge (electrons) moves from battery's negative pole to its positive pole.]

Note that: 

if we use any of the two methods [traditional & real] nothing will change and the rules will also be true, just adding (-) sign or remove it but the value will be the same.
