Problem
Identify the correct reason why the photocurrent decreases when a negative (reverse) potential is applied to the collector in a photoelectric experiment.
(a) The reverse potential increases the effective resistance of the external circuit, thereby limiting the photocurrent
(b) The reverse potential opposes the motion of emitted electrons toward the collector
(c) The reverse potential reduces the intensity of the incident light on the emitter
(d) The reverse potential decreases the frequency of the incident photons
