1.	Find the voltage across the resistor R if VA = -3V and VB = -5V. Use ideal diode model assumption.(a) 0V(b) -3V(c) -5V(d) -4VI got this question in an online interview.I would like to ask this question from Ideal Diode Model in portion Diode Circuit of Analog Circuits
Answer» Correct answer is (a) 0V Easy explanation: In an ideal diode model, the diode is considered as a perfect CONDUCTOR in forward bias and perfect insulator in reverse bias. That is voltage drop at forward bias is ZERO and current through the diode at reverse bias is zero. Since both the diodes are in reverse bias mode, current through the diode is zero and we can consider the diode as an open CIRCUIT. So there is no voltage drop ACROSS resistor R.
