What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
Does a zener diode acts as a switch?
A zener diode cannot be used as switch.
How much voltage appears across a zener diode when it is forward-biased?
That depends on the zener voltage rating:"low voltage" zeners are just a simple single diode, the zener diode"high voltage" zeners contain 2 back to back diodes in one package, the zener diode and an ordinary diode that is reverse biased when the zener diode is forward biased to block forward conduction of the zener and protect it from overcurrent damage if installed backwards by mistakeThus in "low voltage" zeners when forward biased they will have a normal diode drop (e.g. 0.7V), but "high voltage" zeners when "forward biased" they will act open due to the reverse biased blocking/protection diode in series with the zener.
What is the leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
What is the difference between an ideal zener diode and practical zener diode?
Zener diode is heavily doped pn junction diode.
How is the zener diode connected to protect the load?
A: A zener is a diode that if reversed voltage is applied will conduct at a certain voltage. This diode zener therefore will conduct at a preset voltage limiting the over voltage to the diode conducting voltage and no more so the load can see the voltage up to the zener voltage and no more because the zener will sink the extra current from over voltage situation.

Who invented the zener diode?
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.

What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.

What is the difference between p n junction and zener diode?
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
When a 3.3 V zener diode is parallel with a 7 V zener diode what is the break down voltage?
Since they are in parallel, the 3.3V zener diode will "kick in" first when you reach 3.3V, and the circuit will pretty much act the same as if the 7V zener diode isn't there at all.
