how is the flow of current in a cathode ray experiment explained knowing that gases are bad conductors of electricity???.plz anwer fast. i will mark as brainlist!!
ani99ket:
could you please what you want to understand
elaborate*
in the cathode ray experiment electrons were discovered in vaccum sealed discharge tube

The gas in the discharge tube experiment (at low pressure and high voltage) is decomposed. Negatively charged particles are produced which travel, helping the flow of current. Under other conditions,e.g. Atmospheric pressure,no dissociation of gas occurs and no current flows.

From the cathode ray experiment we knew that electrons came out from the negative terminal.
Now these electrons will collide with the gas molecules.
When these electrons strikes the molecules with enough energy the molecules of atoms gains energy and release their electrons and becomes +ve ions.
Due to the electric field the ions and the electrons released start drifting and this leads to the net current in a discharge tube filled with gas.
