Voltage Polarity and Current Direction Summary
The direction of electron flow is from a point of negative potential to a
point of positive potential.
The direction of positive charges, or holes, is in the opposite direction of
electron flow. This flow of positive charges is known as "conventional flow."
Where the electron current enters the load, the voltage is negative.
