Explanation Introduction: Since a diode is a nonlinear device, some portion of the analysis of a diode circuit includes deciding whether the diode is on or off. The various on and off combinations of a circuit involving more than one diode complicates the circuit. Consider two single-diode circuits. Figure 1 shows a diode in series with a resistance. Here V 0 versus V 1 shows the linear nature of this circuit as shown in Figure 2. Until V 1 =V y is achieved the diode does not conduct. Figure 1 Figure 2 In figure 3 the diode remains conducts current for V 1 <V s <V y , and the output is v 0 =v 1 +v y . When v 1 >V s − V y , the diode turns off and the current through the resistance is null, therefore, the outcome remains consistent at V s . Figure 3 Figure 4 The above explanation demonstrates that there are regions where the diode is on or conducting and regions where the diode is off or non conducting. The diode may be on or off for circuit having number of diodes. If we assume that V + > V − and V + − V − > V y , there is at least a possibility that D 2 can be turned on

Analysis of Diode

It is a semiconductor device in electronics applications where only a one-way current is required. It is like a one-way switch that allows current to flow in one direction only. A diode has two terminals, a cathode, and an anode. The cathode is the negat…
