Vedclass · Answer

(A) photoemissive cell consists of two electrodes enclosed in a glass bulb,which may be evacuated or filled with an inert gas at low pressure.When an inert gas is present,the photoelectrons emitted from the cathode collide with the gas atoms,causing ionization. This process increases the number of charge carriers,resulting in a greater current compared to an evacuated cell.Therefore,both the Assertion and the Reason are correct,and the Reason correctly explains why an inert gas is used in such cells.

Assertion: In a photoemissive cell,an inert gas is used.
Reason: An inert gas in the photoemissive cell provides a greater current.
