Vedclass · Answer

(D) diode is forward biased when the potential at the $p$-side (anode) is higher than the potential at the $n$-side (cathode). $(A)$ $p$-side = $-10 \ V$,$n$-side = $0 \ V$. Since $-10 < 0$,it is reverse biased. $(B)$ $p$-side = $-10 \ V$,$n$-side = $-15 \ V$. Since $-10 > -15$,it is forward biased. $(C)$ $p$-side = $4 \ V$,$n$-side = $2 \ V$. Since $4 > 2$,it is forward biased. $(D)$ $p$-side = $-5 \ V$,$n$-side = $-10 \ V$. Since $-5 > -10$,it is forward biased. $(E)$ $p$-side = $0 \ V$ (ground),$n$-side = $2 \ V$. Since $0 < 2$,it is reverse biased. Therefore,circuits $(B), (C)$ and $(D)$ are forward biased.

Which of the following circuits represents a forward biased diode? Choose the correct answer from the options given below.
