Conventional and Electron Flow:

The direction of electron flow is from a point of negative potential to a point of positive potential. The direction of holes, or positive charges, is in the opposite direction of electron flow.  That flow of positive charges is known as conventional flow.  An entire of the electrical effects of electron flow from negative to positive, or from a high potential to a lower potential, are the similar as those that would be created through flow of positive charges in the opposite direction; thus, it is very important to realize which both conventions are in use, and they are essentially equivalent.  Within this manual the electron flow convention is used.
