The resistance of a discharge tube is

Glow in discharge tube is due to

The conditions for the discharge of electricity through gases in a discharge tube is _______.

Assertion : If different gases are filled turn by turn at the same pressure in the discharge tube the discharge in them takes place at the same potential. Reason : The discharge depends only on the pressure of discharge tube and not on the ionisation potential of gas.

The cathode ray particles originate in a discharge tube from the

Electric conduction takes place in a discharge tube due to the movement of

Magnitude of deflection of cathode rays in discharge tube is more when
