From the following graph of photo current against collector plate potential, for two different intensities of light ( I₁ ) and ( I₂ ), one can conclude

Options

  1. A( O I₁=I₂ )
  2. B( I₁>I₂ )
  3. C( I₁ < I₂ )
  4. DComparison is not possible.

Correct answer

C. ( I₁ < I₂ )

Step-by-step solution

For a fixed frequency of incident light, photo-current is directly proportional to the intensity. Thus, from graph, photo current for light of Intensity ( I₂ ) is more than for light of intensity ( I₁ ), Therefore, ( I₁ < I₂ )
