1.	In the circuit shown below current I is 2mA and VB is -1V. The resistor R is 1K. Cut-in voltage of diode is 0.7V. Forward bias resistance is 10Ω. The voltage V is __________(a) 1.3V(b) 0.3V(c) 1V(d) 2VI had been asked this question by my school principal while I was bunking the class.I need to ask this question from Piecewise Linear Model of Diode-2 topic in chapter Diode Circuit of Analog Circuits
Answer» CORRECT choice is (c) 1V For explanation I would say: Since current source is reverse BIAS to the diode current passes through RESISTOR R. VOLTAGE across resistor R is 2mA x 1k = 2V. Since resistor and diodes are parallel net OUTPUT voltage V is VB + voltage across resistor R = -1+2 = 1V.
