With increasing biasing voltage of a photodiode, the photocurrent magnitude :
Option: 1 remains constant
Option: 2 increases initially and after attaining certain value, it decreases
Option: 3 increases linearly
Option: 4 increases initially and saturates finally
I-V characteristic of a photodiode is as follows:
On increasing the potential difference the current first increases and then attains a
saturation.

5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K
A capacitor is made of two square plates each of side 'a' making a very small angle
A solution of m-chloroaniline, m-chlorophenol and m-chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of NaHCO3 to give fraction A. The leftover organic phase was extracted with d
