Current I if V = 5V and -5V when VB = 2V, R1 = 2K, R2 = 4K respectivel

1.	Current I if V = 5V and -5V when VB = 2V, R1 = 2K, R2 = 4K respectively are __________ (Use constant voltage drop model assumption and take VD = 0.5V)(a) 1.3mA, 0.23mA(b) 2.875mA, 0mA(c) 2mA, 0mA(d) 1.423mA, 0 mAI had been asked this question in examination.The above asked question is from Constant Voltage Drop Model-2 in section Diode Circuit of Analog Circuits
Answer» Correct choice is (b) 2.875mA, 0mA Easy 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. When V=5V, diode is in forward bias and NET total voltage becomes 4.5V across R1. Current through branch 1 will be 4.5V / 2K = 2.25mA. Current through branch 2 will be (4.5-2)/4K = 0.625mA. So net current is SUM of these two. THEREFORE, net current is 2.875mA. When V = -5V, the diode is reverse biased and net current flowing is zero.
