List of top Physics Questions on The p-n Junction asked in NEET (UG)

Three identical p-n junction diodes \(D_1\), \(D_2\) and \(D_3\) are connected across a battery as shown in the figure. If the widths of the depletion regions of \(D_1\), \(D_2\) and \(D_3\) are \(W_1\), \(W_2\) and \(W_3\), respectively, then the correct option is:

The barrier potential of a p-n junction depends on:
(a) type of semi conductor material
(b) amount of doping
(c) temperature
Which one of the following is correct?
