1.	If current source I produces a current of 1mA and resistance R=3kΩ, then what is the voltage across the resistor given that diode is ideal?(a) 0V(b) 1V(c) 3V(d) 1.5VThe question was asked by my college director while I was bunking the class.I would like to ask this question from Ideal Diode Model-1 topic in division Diode Circuit of Analog Circuits
Answer» RIGHT option is (a) 0V The best explanation: In 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 current forward biases the diode it acts as a conductor so current through RESISTOR is zero so voltage is zero. Therefore, voltage across resistor is zero.
