In which of the following ciruict the potiential drop across the two p-n juctins are equal take all p-n junctions to be identical

Options

A. (i) and (ii)
B. (i) and (iii)
C. (ii) and (iii)
D. only (iii)

Explanation

In the circuit (ii) both the p-n junction are revers resistance and therfore same potential drop across the junction .
Similarly in the circuit both the p-n junction junction resistance and potential drop.
