1.	In the circuit shown below voltage Vin is 3V and VB is 2V. The resistor R is 1K. Cut-in voltage of diode is 0.7V. The voltage V is __________(a) 0.3V(b) 1V(c) 3V(d) 0VI got this question in an international level competition.I'm obligated to ask this question of Piecewise Linear Model of Diode-2 in section Diode Circuit of Analog Circuits
Answer» The correct option is (d) 0V The best explanation: In piecewise LINEAR model, we can consider diode as a VOLTAGE source of 0.7V along with an IDEAL diode. VIN being applied is 3V, which is greater than 2-0.7 V, and HENCE the diode is reverse biased and considering it OPEN, no output is obtained.
