A 1.5 V battery is added to the photoelectric effect apparatus as shown below. Monochromatic light source Evacuated tube + 1.5 V B Make a sketch of the above circuit and label electrodes A and B according to the type of charge (+ or -) that accumulates (whether the light is on or off). When the light is turned on consider the following questions: • Is the number of electrons emitted from electrode Beach second when there is a battery in the circuit greater than, less than. or equal to the number emitted each second when there is no battery? Explain. • What is the potential difference across the electrodes (AV = VA - VB)? • What does your answer to the above question imply about whether the net charge on each of the electrodes changes? Explain. • Write an expression relating the potential difference AV to the change in kinetic energy of a single electron as it moves from electrode B to electrode A.
