For DC Current, by convention current flows from the positive (+) terminal to the negative (-) terminal. But, this is just convention. read more
Electric current simply means flow of electrons .Therefore according to it the current should flow in the direction of flow of electrons but according to the convention the current flows in the direction of positive charge hence current flows opposite to the direction of electrons. read more
The direction of current flow does not affect what the current does. In general, high school Physics and two year technician programs use Electron Flow. But three year technologist and university engineering programs use Conventional Current. read more
While the direction of the actual electrons flow will be from - to +, the direction of actual holes flow will be from + to - (the same as the conventional current direction) because for the hole current the dq term is positive. read more
