Vedclass · Answer

(B) In circuit $(1)$,the $N$-region of the first diode is connected to the $N$-region of the second diode. This configuration does not allow for a proper series biasing of the junctions.In circuit $(2)$,the $P$-region of the first diode is connected to the $N$-region of the second diode. The external battery is connected such that both diodes are forward-biased (or both reverse-biased depending on polarity),allowing for an equal potential drop across both junctions.In circuit $(3)$,the $P$-region of the first diode is connected to the $N$-region of the second diode. Similar to circuit $(2)$,this configuration allows for a symmetric series connection where the potential difference is distributed equally across the junctions.Therefore,circuits $(2)$ and $(3)$ are the correct connections.

Two $PN$-junctions can be connected in series by three different methods as shown in the figure. If the potential difference across the junctions is the same,then the correct connections will be:
