sir don,t mind please. my question isQuestion 1; In cathode ray tube when pressure is reduced to 0.001 mmHg, original uniform glow disappear and the whole tube is filled up by dark space?Q 2;At this stage(above mentioned) the electrical resistance between the anode and cathode becomes very high and it becomes difficult to maintain the discharge, untill the potential difference between the anode and cathode is very high?
