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! Webt. e. In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage. The term dates from the first three decades of radio (1888-1918). Unlike modern radio stations which transmit sound (an audio signal) on an uninterrupted carrier wave, early radio stations transmitted information by ...
