As the intensity of incident light increases

A

Photoelectric current increases

B

Photoelectric current decreases

C

Kinetic energy of emitted photoelectrons increases

D

Kinetic energy of emitted photoelectrons decreases

Text Solution

Verified by Experts

The correct Answer is:
A

Intensity increases means more photons of same energy will emit more electrons of same energy , hence only photoelectric current increases.
