In metallic solids, electric charge flows by means of electrons, from lower to higher electrical potential. In other media, any stream of charged objects (ions, for example) may constitute an electric current. To provide a definition of current independent of the type of charge carriers, conventional current is defined as moving in the same direction as the positive charge flow. So, in metals where … Webcurrent, IDS. Fig. 4 - Sketch Showing Breakdown of Gate Charge The slope of the Miller Plateau is generally shown to have a zero, or a near-zero slope, but this gradient depends on the division of drive current between C gd and Cgs. If the slope is non-zero then some of the drive current is flowing into Cgs.
