Which of the following condition is suitable for cathode ray discharge

1.	Which of the following condition is suitable for cathode ray discharge tube?(a) Low pressure, high voltage(b) Low pressure, low voltage(c) High pressure, low voltage(d) High pressure, high voltageI have been asked this question in examination.My query is from Discovery of Sub-atomic Particles in portion Structure of Atom of Chemistry – Class 11
Answer» Right choice is (a) Low pressure, high voltage The EXPLANATION is: The suitable CONDITIONS of cathode ray discharge TUBE are low pressure and high pressures. Pressure can be adjusted by evacuated tubes. High voltage is applied across ELECTRODES and current starts flowing through the tube.
