Question

NTA AbhyasNTA Abhyas 2020

Solution:

The value of photocurrent depends on the intensity of incident light. Hence, when the intensity of incident light increases, then the value of photocurrent is increased. i.e.
the intensity of light $\left(I\right) \propto $ photocurrent
Solution
From graph
$I_{1} < I_{2}$
