Q. The variation of photoelectric current given by the photocell, with the intensity of light, is give by a graph, which is a straight line with

A) $+$ve slope with intercept on current axis
B) $-$ve slope with intercept of current axis
C) $+$ve slope passing through origin
D) $-$ve slope passing through origin
Explanation

(c) Photoelectric current $\propto$ intensity of incident light. Therefore, the graph is a straight line having positive slope passing through origin
