Use whatever exponential model you like to calculate the actual forward voltage of the diode at that specific current level. Change your ideal voltage source voltage to the calculated diode voltage. Repeat until the values of diode voltage and current converge to your satisfaction. Or, run a SPICE simulation.Answer: C. Clarification: 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 V in and V B are opposite net voltage is 3V. Voltage at R 1 is 3V so current is 1.5mA. Voltage at R 2 is 3-0.5 = 2.5V.Voltage drop formulas. Let’s see two most common methods for calculation of voltage drop – approximate and exact methods: 1. Approximate method. Voltage drop EVD = IR cosθ + IX sinθ where abbreviations are same as below “Exact Method”. 2. Exact method #1. If sending end voltage and load PF are known.Mar 6, 2015 · With diode 1 on and diode 2 off, the V terminal is at -5 V since there's no voltage drop across the 5k resistor due to there being no current, which means the voltage drop across diode 2 is 5.7 V since it's 0.7 V at the shared node with diode 1. Again, this isn't consistent with the model since no current flows through diode 2.

Answer: B. Clarification: 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. 4.4.3 Diode Circuit Models Diodes present a circuit analysis challenge compared to linear devices (such as resistors) owing to the complex shape of the diode curve. Unlike a resistor, there isn’t an exact analytical expression relating voltage and current in a diode that can be written down and used in KVL and KCL and node voltage analyses described in chapter 3.2.
