1.	In the given circuit input voltage Vin is 3V and VB is 1.5V. The resistance R is 1.5K. Cut-in voltage of diode is 0.5V. Forward bias resistance is 10Ω. The Voltage V will be ____________(a) 2.7V(b) 3V(c) 0.8V(d) 1.5VThe question was asked in an online quiz.My question is from Piecewise Linear Model of Diode-2 in section Diode Circuit of Analog Circuits
Answer» Correct answer is (b) 3V For explanation: In PIECEWISE LINEAR model, we can consider diode as a voltage source of 0.5V along with an IDEAL diode. VIN being applied is 3V, which is greater than 1.5-0.5 V, and HENCE the diode is reverse biased and input appears at output.
