What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
How is zener diode different from p-n junction diode?
A p-n junction diode is made of a crystal of semiconductor. Impurities are added to it to create a region on one side that contains negative charge carriers (electrons), called n-type semiconductor, and a region on the other side that contains positive charge carriers (holes), called p-type semiconductor. A Zener diode contains a heavily doped pn junction allowing electrons to tunnel from the valence band of the p-type material to the conduction band of the n-type material. A reverse biased Zener diode will exhibit a controlled breakdown and let the current flow to keep the voltage across the Zener diode at the Zener voltage.
What type of biasing must be used when a zener diode is used as a regulator?

What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
What is zener diode and for what it is used?
Zener Diode is nothing but a Crystal P-n junction diode in which the P type and n-type layers are heavily doped.Zener diode is mainly used as voltage regulator its forward charaqcteristic is same as normal p-n junsction diode but its reverse Characteristic is different that when the reverse region reaches knee region in spite of changes in current the voltage remains the same
Can a lower voltage zener diode be used?
It depends on the design of the circuit.
Is zener diode a voltage amplifier or currentlimitig circuit or osilator circuit?
The zener diode is neither a voltage amplifier nor a current limiting device but can be used in oscillator circuits to supply a constant output voltage.
Does a zener diode acts as a switch?
A zener diode cannot be used as switch.
What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
What type of current is used in zener diode?
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.

Is it can say as a 4.9v zener diode If you connect seven 0.7v silicon diodes in forward bias in series?
When the design says 4.9v zener diode that is all I would put. The more complicated an alternative you try the more things that can go wrong. A silicon diode is not the same as a zener diode, and cannot be used to replace a zener, with reasonable expectation that the circuit will continue to operate as designed.
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.
Can zener diode used as rectifier?
Yes **************************************** Yes they can but there are pitfalls. A normal diode will have a high reverse breakdown voltage. A zener has a relatively low breakdown voltage (its "zener"voltage). If a zener diode is used as a rectifier it must have a zener voltage at least twice the peak of the applied a.c.
What is the difference between rectifier diode and zener diode?
A: They are both diodes. The difference lies in the application. A rectifier is used to rectify AC current into pulsating current. The zener diode is used to regulate a voltage source to the zener voltage when connected in the reverse direction. ************************************************************** If you look at the characteristic curves of a rectifier diode and a zener diode, you will see that they are similar, but the reverse curve of the zener has a much sharper bend at what is called the "knee". It is at this point on the zener's curve at which it operates.
