TWO CONVENTONS OF CURRENT FLOW

Two Conventions of Current Flow

There are two ways of looking at the current flow, the electron current flow, and the conventional current flow.

Electron current flow is the flow of current from low to high potential, or from negative to positive. Benjamin Franklin, an American scientist, studied electricity and was one of the first to actually describe current flow. According to him, the positive charge flows in conductor from high to low potentials or from positive to negative as shown in figure 3. This theory of current flow is called as the conventional current flow. It makes no difference which principle is used to describe electricity for all the effects expected are the same.
