WebFeb 1, 2024 · Electrons and current flows. Maximum flow is referred to as “saturation” reflecting the temperature and physical constraint where the anode is pulling in all of the electrons that the cathode can produce. By altering the voltage of the grid, we can “open and close the valve,” allowing current to flow more or less. Awesome! WebBut maybe check out some of these other Projects and Stories.
