Medium· Semiconductor Diode (P-n Junction under Forward Bias, p-n Junction Diode)· +4 / −1
In the given circuits (a), (b) and (c), each made of two p-n junction diodes connected in series with their polarities as shown in the figure, the potential drop across the two p-n junctions are equal in:
(Figure: circuit (a) has both diodes oriented the same way, P-N followed by P-N, in series aiding; circuit (b) has the diodes in a back-to-back orientation, P-N followed by N-P; circuit (c) has both diodes oriented the same way, N-P followed by N-P, mirroring circuit (a).)
