In a discharge tube at 0.02 mm, there is a formation of

In a discharge tube, the source of positive rays 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 electric current existing in a discharge tube is 2.0(mu)A. How much charge is tarnsferred across a cross-section of the tube in 5 minutes ?

The electric current existing in a discharge tube is 2.0(mu)A. How much charge is tarnsferred across a cross-section of the tube in 5 minutes ?

An electric current of 2.0 mu A exists in a discharge tube. How much charge flows across a cross-section of the tube in 5 minutes ?

Glow in discharge tube is due to

The mean free path of electrons in the gas in a discharge tube is inversely proportional to the pressure inside it. The Crookes dark space occupies half the length of the discharge tube when the pressure is 0.02 mm of mercury. Estimate the pressure at which the dark space will fill the whole tube.
