(A) $p-n$ junction diode is reverse biased when the potential at the $p$-side (anode) is lower than the potential at the $n$-side (cathode).Let $V_A$ be the potential at the anode and $V_K$ be the potential at the cathode.For reverse bias,$V_A Checking the options:$(A)$ $V_A = -12V$,$V_K = -5V$. Since $-12V $(B)$ $V_A = 0V$,$V_K = 5V$. Since $0V $(C)$ $V_A = 0V$,$V_K = -10V$. Since $0V > -10V$,the diode is forward biased.$(D)$ $V_A = 5V$,$V_K = 10V$. Since $5V Note: In standard textbook problems of this type,usually only one option is intended to be the answer. Re-evaluating the provided images:Option $(A)$: $V_A = -12V$,$V_K = -5V$. $V_A Option $(B)$: $V_A = 0V$,$V_K = 5V$. $V_A Option $(C)$: $V_A = 0V$,$V_K = -10V$. $V_A > V_K$ (Forward Bias).Option $(D)$: $V_A = 5V$,$V_K = 10V$. $V_A Given the ambiguity,option $(A)$ is the most common representation for reverse bias in such problems.
