The cathode of a photoelectric cell is changed such that the work function changes from 
to 
. If the current before and after change are 
and 
, all other conditions remaining unchanged, then (assuming 
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
The work function has no effect on current so long as 
. The photoelectric current is proportional to the intensity oflight. Since there is no change in the intensity of light, therefore
