A2.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. 2. From the sounds of it, the diode model you are using is the simple "ideal diode" with a fixed forward voltage. This model is an open circuit when VAnode −VCathode < VD V Anode − V Cathode < V D (reverse biased), and a fixed VD V D voltage supply otherwise (forward biased).
