Question

The curves (a), (b), (c) and (d) show the variation between the applied potential difference (V) and the photoelectric current (i), at two different intensities of light (I₁ > I₂) In which figure is the correct variation shown.

Answer 1

The correct option is Option B.

Explanation:

intensities I₁, I₂ and I₁ > I₂

as current ∝ intensity hence i ∝ I

 i₁ > i₂

stopping potential V_o does not depend on velocity hence V_o is same.

∴ curve is (B)
