Problem
In a photoelectric experiment set up, photons of energy 5 eV falls on the cathode having work function 3 eV.
(a) If the saturation current is iA=4μA for intensity 10−5 W/m2, then plot a graph between anode potential and current.
(b) Also draw a graph for intensity of incident radiation 2×10−5 W/m2.
