Question : 8 of 14

Marks: +1, -0

SECTION - B

Plot a graph showing the variation of photo electric current, as a function of anode potential for two light beams having the same frequency but different intensities

I_1

and

I_2 (I_1 > I_2)

. Mention its important features.

Solution: 👈: Video Solution

Variation of photoelectric current as a function of anode potential:

Important features:

(i) As intensity increases, saturation current increases.

(ii) Stopping potential is independent of the intensity of light.
