What do you understand by zener diode?
It is a voltage regulator
How do you find the value of a zener diode?
It is depend on your requirement .suppose you need a voltage regulator of 5V than you need 5V Zener diode.
How do you xxplain the zener shunt regulator?
zener diode is a special type of pn junction diode that work in breakdown region . There are two types of brekdowns in zener i.e avlanche breakdown and zener breakdown depending on the doping concentration. A zener diode in an on state can be considered as a voltage source ,equal to its zener voltage n hence act as an voltage regulator
What is the zener point?
A diode (some people incorrectly call them rectifiers) is a semiconductor device that allows a current to flow in one direction. A Zener diode allows a reverse to current to flow at a defined voltage. A common application for them is as a voltage regulator. Named for C M Zener , US Physicist. A zener diode is a diode and like all diodes it will conduct in both directions. If a reversed voltage is applied it will breakdown and conduct current. Most diodes when they breakdown the reversed voltage cannot be predictable. However a zener diode when they do breakdown in the reverse voltage mode that voltage can be made as predictable and remain +/- % of the breakdown voltage. Therefore this steady voltage can be used as a regulator for instance or a definite voltage drop if need be.
What is the special properties of a diode?
in the negative biasing it gives the constant voltage irrespective of limited current.......the voltage it provides in the negative biasing is known as 'zener voltage' due to this property zener voltage is used as voltage regulator........voltage regulator is a circuit which gives constant output even the input is changing.
Is it pn junction diode used as voltage regulator?
zener diode
What do you understand by zener diode?
It is a voltage regulator
When biased correctly a zener diode acts as?
a diode and it has a constant voltage across it ANSWER: acts as a voltage regulator if enough current flows to create a breakdown voltage.
What is V-I characteristics of zener diode?
Work in reverse bias.(breakdown at a particular voltage to keep the volt. constant so used as voltage regulator) same as diode when forward biased.
When operating as a voltage regulator the breakdown in a Zener diode occurs due to which effect?
avalanche
Why zener diode is used as voltage regulator?
A: At one time it was used for a regulator because in the reverse voltage breakdown it has the characteristic of keeping the voltage constant as voltage is increased. IT has being replaced by many three terminal regulator with much better regulation and temperature coefficient
How a voltage regulator works?
A Voltage Regulator is just a Zener Diode that is wired across the alternator terminals. ... no. Doing this will blow the zener - don't try it at home or anywhere else.

What does the diode trio do?
The old delco diode trio takes the 3 phase rectified voltage from the rectifier bridge and and joins it back into one single phase; readys it for the voltage regulator.
How do you find the value of a zener diode?
It is depend on your requirement .suppose you need a voltage regulator of 5V than you need 5V Zener diode.
What is the function of zener dioed?
The function of a zener diode is for it to act as a voltage regulator in the breakdown region.
