From the circuit and the diode characteristics given alongside, and assuming R=2k, what is the value of diode voltage at the operating point?(a) 0.78 V(b) 10 V(c) 0 V(d) 1vI got this question in an interview for job.My doubt stems from Load Line Analysis in portion Diode Circuit of Analog Circuits

Answer»

The correct CHOICE is (a) 0.78 V

Easy explanation: On DRAWING the LOAD line with the equation: VD = ED + IDRD, we get the operating point with the VALUE of at voltage at around 0.7-0.8 V. Hence, VDq=0.78 V.
