Q.
The curves (a), (b) (c) and (d) show the variation between the applied potential difference $(V)$ and the photoelectric current $(i),$ at two different intensities of light $\left( I_{1} > I_{2} \right).$ In which figure is the correct variation shown
A)
B)
C)
D)
Explanation
(b) $I_{1} > I_{2}$ (given) $\Rightarrow i_{1} > i_{2}\ \lbrack\because i \propto I\rbrack$
and stopping potential does not depend upon intensity. So its value will be same $\left( V_{0} \right)$
