zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
The dynamic resistance of a diode, be it zener or otherwise, will be different from its static resistance because a diode is not a resistor, and resistance is not a function of current flow. It is a diode, and a diode has its own characteristic voltage to current curve, forward and, in the case of a zener, reverse.
If the zener diode is in zener breakdown the voltage across the zener diode remains constant regardless of current (for the ideal zener diode). Real zener diodes have parasitic resistance that causes the voltage across the zener diode to increase slightly with increased current, but due to temperature dependant variations in this parasitic resistance as well as temperature dependant variations in the zener breakdown voltage, this change in voltage in real zener diodes cannot be described by a simple linear factor.
Zener diode can be defined as diode which allows current to flow in the forward direction in the same method as an ideal diode, but will also allow it to flow in reverse direction when the voltage is above definite value known as the breakdown voltage
A zener diode cannot be used as switch.
Zener diode is heavily doped pn junction diode.
zener diode
The Zener diode has the characteristics of a constant voltage source.
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
A: An ideal current source can be defined as a short with immense current capabilities A zener has no such capabilities

There are thousands of different zener diode types...use the internet to locate a data sheet for a particular type.
Zener diode can be defined as diode which allows current to flow in the forward direction in the same method as an ideal diode, but will also allow it to flow in reverse direction when the voltage is above definite value known as the breakdown voltage
A zener diode passes drect current, and the point of a zener diode is that the voltage across it stays nearly constant over a range of different currents, so it can provide a supply of stabilised voltage.
A zener diode cannot be used as switch.
SILICON same as any other diode but with different characteristics
