Question

Maximum photoelectric current at particular intensity of incident radiation, which becomes
independent of anode potential is known as _________.

Answer 1

answer:saturation current

Explanation:

Answer 2

Maximum photoelectric current at particular intensity of incident radiation, which becomes independent of anode potential is known as Saturation Current.

• At a particular intensity, certain number of photons strike the tube, leading to emission of electrons, which are accelerated by anode potential.
• Since a photon can lead to emission of only one electron, the maximum number of emitted electrons are fixed.

Hence, a Saturation Current exists irrespective of the value of anode potential.
