Vedclass · Answer

(A) An ideal $P-N$ junction diode acts as a closed switch (zero resistance) when forward-biased. In this state,the entire voltage $V$ of the source appears across the resistor $R$.When the diode is reverse-biased,it acts as an open switch (infinite resistance). In this state,no current flows through the circuit,and the voltage drop across the resistor $R$ is $0 \ V$.

Which of the following options is correct for the $P-N$ junction diode shown in the figure?
