WebTranscript. The positive sign for current corresponds to the direction a positive charge would move. In metal wires, current is carried by negatively charged electrons, so the positive current arrow points in the opposite direction the electrons move. This has been the sign convention for 270 years, ever since Ben Franklin named electric ... WebUsage. The Flow Direction tool supports three flow modeling algorithm: D8, Multiple Flow Direction (MFD), and D-Infinity (DINF). The D8 flow method models flow direction from each cell to its steepest downslope neighbor. The output of the Flow Direction tool using the D8 flow direction type is an integer raster whose values range from 1 to 255.
