(c) Approximately how much will the current change …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.The constant voltage drop model (assuming 0.7 V for silicon) is fine for most applications. Also, using the constant drop model enables rapid analysis of circuits employing diodes.

Two diodes with saturation ...Mar 3, 2020 · So again, the only difference between the constant voltage drop and the ideal model is the fact that you put in a voltage source to say, okay, we're losing 0.7, or whatever your assumption is, 0.7 volts across this diode. And in most cases, it won't make a difference, but on occasion it will, it definitely will make things more complicated for you. 2.
