The cathode of a photoelectric cell is changed such that the work function changes from W₁ to W₂ (W₂ > W₁). If the current before and after changes are I₁ and I₂, all other conditions remaining unchanged, then (assuming hν > W₂)

1. I₁ = I₂
2. I₁ < I₂
3. I₁ > I₂
4. I₁ < I₂ < 2 I₁

Correct Option: A

The work function has no effect on photoelectric current so long as hν > W₀. The photoelectric current is proportional to the intensity of incident light. Since there is no change in the intensity of light, hence I₁ = I₂.
