Vedclass · Answer

(B) diode is reverse biased when the potential at the $p$-terminal (anode) is lower than the potential at the $n$-terminal (cathode).$(1)$ $p$-terminal = $5 	ext{ V}$, $n$-terminal = $0 	ext{ V}$ (ground). Since $5 	ext{ V} > 0 	ext{ V}$, it is forward biased.$(2)$ $p$-terminal = $-20 	ext{ V}$, $n$-terminal = $-10 	ext{ V}$. Since $-20 	ext{ V} $(3)$ $p$-terminal = $15 	ext{ V}$, $n$-terminal = $10 	ext{ V}$. Since $15 	ext{ V} > 10 	ext{ V}$, it is forward biased.$(4)$ $p$-terminal = $20 	ext{ V}$, $n$-terminal = $-5 	ext{ V}$. Since $20 	ext{ V} > -5 	ext{ V}$, it is forward biased.Thus, the diode is reverse biased in Figure $(2)$.

In which of the following figures is the diode reverse biased?
