Vedclass · Answer

(A) To measure the dynamic resistance of a $p$-$n$ junction diode,the diode must be in a forward-biased condition.In a forward-biased circuit,the $p$-terminal (anode) of the diode is connected to the positive terminal of the voltage source,and the $n$-terminal (cathode) is connected to the negative terminal (or ground).Looking at the provided options:- In option $A$,the diode $D_4$ is forward-biased as the positive terminal of the battery is connected to the $p$-side.- In option $B$,the diode $D_2$ is reverse-biased.- In option $C$,the diode $D_3$ is forward-biased,but it is connected to a capacitor,which blocks $DC$ current.- In option $D$,the diode $D_1$ is reverse-biased.Therefore,the circuit in option $A$ represents the correct forward-biased configuration for measuring dynamic resistance.

Which of the diode circuits shows the correct biasing used for the measurement of the dynamic resistance of a $p$-$n$ junction diode?
