The current I through the circuit if we consider diode in constant vol

1.	The current I through the circuit if we consider diode in constant voltage drop model is? (Take VD as 0.5V)(a) 2mA(b) 2.5mA(c) 3.5mA(d) 1mAI have been asked this question by my school principal while I was bunking the class.My doubt is from Constant Voltage Drop Model-1 topic in chapter Diode Circuit of Analog Circuits
Answer» The correct option is (b) 2.5mA Best explanation: In constant voltage drop model at FORWARD BIAS DIODE can be replaced as a cell and in reverse bias diode can be avoided by considering the terminals are open. Since D1 is in forward biased there will be a voltage drop of 0.5V. So net voltage will be 2.5V and HENCE current is 2.5mA.
