Photo Electric Effect

Question

The curves (a), (b), (c) and (d) show the variation between the applied potential difference (V) and the photoelectric current (l), at two different intensities of light ( $I_{1} > I_{2}$ ) but of same frequency. In which figure is the correct variation shown?

Easy

A
B
C
D

Solution

$\begin{array}{l} I_{1} > I_{2} (given) \Rightarrow i_{1} > i_{2} (∵ i \propto I) \\ and stopping potential does not depend upon intensity . \\ So its value will be same (V_{o}) . \end{array}$
