Click For Summary
Diodes are modeled as open circuits in reverse bias and short circuits in forward bias. The discussion revolves around a simulation of a circuit with real diodes, focusing on the behavior of the output voltage (Vout) and voltage across the diode (Vx). A key question raised is whether the circuit remains in state 1 after entering it or if it transitions to a different state. The impact of reversing diode D2 on the circuit's behavior is also explored. Understanding these dynamics is crucial for accurate diode modeling in circuit simulations.

In part e of the question, does the circuit stay in state 1 after it gets into state one or does it change states?

This is a simulation of the specified circuit, using real diodes. Red is Vout, green is Vx.
Now let's turn D2 around and see what happens:
