Question

Which of the following statement is correct?

• A. The photocurrent increases with intensity of light
• B. The stopping potential increases with increase of incident light
• C. The current in photocell increases with increasing frequency
• D. The photocurrent is proportional to the applied voltage.

Answer 1

Answer: (A)

Since the emission of photoelectrons is directly proportional to the intensity of the incident light, therefore photocurrent increases with the intensity of light.
