Vedclass · Answer

(B) diode is in a forward-biased condition when the potential at the $p$-terminal (anode) is higher than the potential at the $n$-terminal (cathode).Let $V_A$ be the potential at the anode and $V_K$ be the potential at the cathode.For forward bias,the condition is $V_A > V_K$.Checking the options:$(A)$ $V_A = 0 \ V$,$V_K = 2 \ V$. Here $V_A $(B)$ $V_A = 0 \ V$,$V_K = -2 \ V$. Here $V_A > V_K$ $(0 > -2)$,so it is forward-biased.$(C)$ $V_A = -5 \ V$,$V_K = -2 \ V$. Here $V_A $(D)$ $V_A = 5 \ V$,$V_K = 12 \ V$. Here $V_A Therefore,option $(B)$ is the correct answer.
