Final answer:
False. A current is not created in a photoconductive cell if only one electron is expelled from a photon strike.
Step-by-step explanation:
False
A current is not created in a photoconductive cell if only one electron is expelled from a photon strike. The photoelectric effect occurs when multiple electrons are expelled from the photoconductive material due to the absorption of photons with enough energy. This phenomenon is used in devices like solar panels to convert light energy into electrical energy.
