It is depend on your requirement .suppose you need a voltage regulator of 5V than you need 5V Zener diode.
The zener voltage is typically specified at a specific zener diode current, often referred to as the test current (Izt). This value is usually found in the diode's datasheet and represents the current at which the zener voltage is stable and within specified limits. Operating the zener diode at this current ensures accurate voltage regulation, while deviations in current can lead to variations in the output voltage.
zener diode is a revers bias diode which used for voltage regulation.
to limit the voltage or regulate the same.

zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode

Zener diode is heavily doped pn junction diode.
The zener diode is optimized for reverse breakdown voltage accuracy and stability. This value and its tolerance is specified in more detail than a normal diode.
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
It depends on the particular diode. They come in all different values.
A zener diode cannot be used as switch.
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
zener diode is a revers bias diode which used for voltage regulation.
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
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
