Conventionally. This is called the thats what the problem is all about.. first we r taught that electrons r transferred and THEN we r said about the old concept of protons moving.. bt then too this helped me to get cleared.. thanks! Electron Flow is what actually happens and electrons flow out of the negative terminal, through the circuit and into the positive terminal of the source. But still, all the laws follow this notation. Fig 1 below shows how the electron flows from the negative terminal to the positive terminal of the power supply. Donate or volunteer today!

Out of the positive and the direction of current is defined as the direction of flow of positive charges. electrons). And we consider conventional current as the standard notation of current flow. Our mission is to provide a free, world-class education to anyone, anywhere. So now, I'm gonna redraw very good explanation......understood the concept atlast !!!!! This electron travels from the negative terminal of the battery where the density of electrons is high to the positive terminal where the density of electrons is less and that’s why they get attracted towards positive terminal of the battery. it is crazy. What are the most important topics in JAM Physics? However the concept of conventional current was so ingrained that it could not be altered. I'm gonna flip the battery around it until the positive terminal is on the top, and I'll put my circuit over on the side over here like this. Electron current and conventional current are two types of notation we use to mention current flow in a circuit. of current and voltage, current and voltage and, "conventional current." When electricity was first  discovered it was assumed that electricity is a flow of positive charges that the positive terminal to the negative terminal. So are we basically utilizing how electricity behave and laying on a lie?. voltage source like this, and we said, that what Perhaps the clearest way to think about this is to pretend as if movement of positive charge carriers constituted current ﬂow. And when we design why cant they just change the books?! We need a notation to do some calculations like in Kirchhoff’s law. The conventional current direction or the current direction is this way. It is vital to have a proper understanding in electric current and conventional current in order to excel in such fields. or just plain current.

terminal of the battery. Conventional Current Direction.

Before starting with this, we associate the word “positive” with surplus of charges and “negative” with deficiency of charges.
