Basic DC Theory VOLTAGE POLARITY AND CURRENT DIRECTIONFigure 31 Voltage PolaritiesSummaryThe important information in this chapter is summarized below.Voltage Polarity and Current Direction SummaryThe direction of electron flow is from a point of negative potential to apoint of positive potential.The direction of positive charges, or holes, is in the opposite direction ofelectron flow. This flow of positive charges is known as "conventional flow."Where the electron current enters the load, the voltage is negative.Rev. 0 Page 41 ES-02
