In a photoelectric experiment, light of frequency \(f\) shines on a metal plate inside an evacuated tube. The potential difference \(V\) between the collector plate and the emitting plate is varied, and the resulting photocurrent \(I\) is recorded. The experiment is conducted twice using light of the same frequency \(f\) (which is above the metal's threshold frequency), where Trial 1 uses light of intensity \(I_1\) and Trial 2 uses light of intensity \(I_2\) such that \(I_1 > I_2\). Which of the following correctly describes the graph of current \(I\) as a function of potential difference \(V\) for the two trials?
