The cathode of a photoelectric cell is changed such that the work function changes from \( W_{1} \) to \( W_{2} \) \( \left(W_{2}W_{1}\right) \). If the current before and after change are \( I_{1} \) and \( I_{2} \), all other conditions remaining unchanged and assuming \( \left(E_{1}W_{2}\right) \), then
(a) \( I_{1}=I_{2} \)
(b) \( I_{1}I_{2} \)
(c) \( I_{1}I_{2} \)
(d) \( \frac{W_{1}}{W_{2}}=\frac{I_{1}}{I_{2}} \)
