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 happens when the temperature of a forward biased diode is increased?

What happens depends on the temperature coefficient of the diode. If that diode has a positive temperature coefficient, it resistance increases with increased temperature. A diode with a negative temperature coefficient does the opposite.

When current through a zener diode increases by a factor of 2 by what factor does the voltage across the zener diode increase?

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.

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.

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.
