In this article I have discussed in detail what is the diode ideal and practical model. How do we treat the diode as a circuit element. Which diode model is best while analyzing or designing a circuit. Basically diode is a pn junction device and we can analyze any circuit in three possible ways when that circuit contains a diode in it.

Determine whether each silicon diode in Figure 2-92 is forward-biased or reverse-biased.
6. Determine the voltage across each diode in Figure 2-92, assuming the practical model.
7. Determine the voltage across each diode in Figure 2-92, assuming an ideal diode.
8. Determine the voltage across each diode in Figure 2-92, using the complete diode model with
rd = 10ohm and rR = 100 Mega ohm
