In the following Fig., , , and (e), which of the diode are forward biased and which are reverse biased and why?
Text Solution
Verified by Experts
To decide the biasing of the junction diode we draw the equivalent circuits of various cases and note the effective potentials at the ends A and B of junction diode. The equivalent circuits of above cases are shown in Fig., , , and (e) From these circuits we note that Reverse biased Forward biased Reverse biased Forward biased (e) Forward biased.
