It is an equation that describes the I-V characteristic of a diode. In other words, how the current depends on the voltage.The Shockley diode equation uses an exponential expression. See the Wikipedia article on "Shockley diode equation" for more details.
However, for many practical purposes, it's accurate enough to think of a diode as being "open" in the "forward" direction (no voltage drop), and having a voltage drop of about 0.7 V (in the case of diodes made from silicon) in the "reverse" direction.

How do you find the ac resistance of a diode?
The ac resistance of a diode is found using the equation: (The change in Vd)/(The change in Id) An easier was is to use the Equation: 26mV / Id. This is a general form as the ac resistance of a diode change as the temperature changes.
What is the incremental resistance obtained from the diode equation?
The incremental resistance of a diode is the inverse of the slope of the V-I curve at the operating point.
How is zener diode different from a conventional diode or ideal diode?

PN junction diode made of silicon is the value of voltage depends exponentially on the current through the diode.?
current depends exponentially on voltage: diode equation (approx.) Idiode=k (exp (Vdiode/Vth)-1) k=constant (saturation current, something like a femto ampère) Vth=KT/q => 25.8 mV @ T=300 K, Vth is thermal voltage K=Boltzmann's constant T=junction temperature (Kelvin) q=electron charge
