No diodes do not increase voltage the most common diode can be thought pf as a one way gate that will only allow the flow of electricity in one direction.
these diodes can be used in groups to form a rectifier which converts ac to dc

What is the cutting voltage of a silicon diode?
It is not 'Cutting voltage' but it is Cut-in voltage'. It is the voltage at which the diode turns ON. For silicon it is 0.7v. After reaching 0.7V diode current starts increasing rapidly for little increase in voltage.
What is the explanation for the Operation of varicap diode?
The capacitance of a varicap diode varies as the reverse voltage to the diode changes. As you increase the reverse voltage, the capacitance decreases. And vice versa.
What is zener break down voltage?
The point in the forward operating region of the characteristic curve where conduction starts to increase rapidly is called Knee voltage of a PN Junction Diode.The breakdown voltage of a diode is the minimum reverse voltage to make the diode conduct in reverse.(or) Breakdown voltage is a parameter of a diode that defines the largest reverse voltage that can be applied without causing an exponential increase in the current in the diode.-- Dinakar
Definition of cut in voltage of diode in electronics?
zener cut in voltage
Why breakdown voltage increase in reverse biased p-n junction diode?
when the p-n junction is heavily doped p-n junction diode has very sharp 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.
Is it possible to reduce the cut in voltage of a diode?
No,it is not possible to reduce or increase the cut in voltage of the diode after the manufacturing of the diode but we can design zener diodes of various values of cut in voltage.But it is able to do that only at the time of manufacturing
Explain how Zener Diode is used as a voltage regulator?
A zener is a diode that has the property when reversed bias to breakdown at a specific voltage this voltage will remain constant as current increase. It is important to be aware that the diode will need to dissipate heat while it is operating. The power is the current flowing through the diode multiplied by the voltage across the diode. For zener diodes with a high reverse breakdown voltage, it can be seen that a lot of power may need to be dissipated for a relatively low current. We can use the constant voltage as a reference voltage. Either a component can be powered directly from the reference voltage created or additional components can be used to increase the available current.

Why breakdown voltage increase in reverse biased p-n junction diode?
when the p-n junction is heavily doped p-n junction diode has very sharp breakdown voltage.
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.
What is dropper diode voltage regulator?
The dropper diode voltage regulator is a type of voltage regulator. It is comprised of a single diode that serves as the voltage regulating device.
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
How do you explain the stability of output voltage in spite of input voltage changing at zener diode?
In the zener region of a diode, there is a relatively flat, low slope line for voltage as a function of current. As a result, increasing current in the zener region does not result in a significant increase in voltage - hence, voltage stability.
