MCQ

The cathode of a photoelectric cell is changed such that the work function changes from $W_1$ to $W_2 (W_2>W_1)$. If the current before and after change are $I_1$ and $I_2,$ all other conditions remaining unchanged, then $($assuming $hn > W_2)$

✓
$I_1=I_2$
B
$I_1$
C
$I_1>I_2$
D
$I_1$

✓

Answer

Correct option: A.

$I_1=I_2$

$I_1=I_2$
