V R Tube Characteristics

V R Tube Characteristics ·      To draw characteristics of VR Tube , complete with power supply and Tube mounded on base. ·      Voltage Regulator (or VR) valves are ingenious devices designed to maintain a constant voltage across their terminals over a range of currents. ·      VR tubes have a cold cathode and contain gases at low pressure rather than the conventional high vacuum used in amplifying valves. ·      The internal gasses are deliberately chosen to ionize (conduct) at a particular predefined voltage and is this mechanism that provides the voltage regulation.  ....
