Question

how does the voltage affect the photoel ectric effect


​

Answer 1

The photoelectric cell is placed between the electrodes of an external variable voltage, the control voltage. It can be observed that this external voltage affects the magnitude of the photocurrent. If the voltage is positive (the cathode is negative) the photocurrent flows.
