(A) Draw a circuit diagram to study I-V characteristic of a photocell
(B) When radiation of same intensity and different frequencies are incident on cathode of photocell, how does saturation current vary with anode potential
(C) When radiation of same frequency and different intensity are incident on the cathode of photocell, how does the stopping potential change with anode potential.
(D) Drawing a graph show variation in photoelectric current with variation i the intensity of incident radiation keeping their frequency constant
