The cathode of a photoelectric cell is changedsuch that the work function changes from W1 toW2 (W2 > W1). If the current before and afterchanges are I1 and I2, all other conditionsremaining unchanged, then (assuming hν > W2)[1992]
  • a)
    I1 = I2
  • b)
    I1 < I2
  • c)
    I1 > I2
  • d)
    I1 < I2 < 2 I1
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
The cathode of a photoelectric cell is changedsuch that the work funct...
The work function has no effect on
photoelectric current so long as hv > 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.
