Question

what are the conditions maintained in a discharge tube for the generation of cathode rays??​

Answer 1

Answer:

The usual conditions maintained in a discharge tube are 10kv to 50 kv DC potential between cathode and anode and a gas pressure of less than 0.014 Pa.

Answer 2

Answer:

Low pressure and High voltage should be maintained in a discharge tube for the generation of cathode rays.

Explanation:

• Low pressure is necessary because if the pressure increases in the tube then the atom present in the tube will increase and electron will started to collide with these atoms and this will create an obstruction.
• Low pressure is maintained to provide the enough space between the gas molecules so that the ions forming in the tube accelerate at high speed and gives positive molecules whenever strike to a gas molecules.
• On getting High voltage across the tube,means an electron can gain more kinetic energy between the collisions.
