What happens in the circuit when a1N4001 diode experiences its breakdown voltage of 50V?
If a diode breaks down in the reverse direction then, providing there is current-limiting resistance, nothing will happen to the diode. If there is no such current-limiting resistance the diode will be destroyed. Heat is the only enemy of a semiconductor of this type.
What is an Esaki diode?
A diode is a semiconductor electrical component that allows an electric current in only one direction. A tunnel diode, or Esaki diode, is a special type of diode that can operate very quickly using quantum tunneling, allowing it to work even with microwave frequencies (current switching direction billions of times per second).
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
What are the characteristic of photo diode?
A photodiode is a type of photodetector capable of converting light into either current or voltage, depending upon the mode of operation. Its characteristics is same as that of an ordinary diode, except that it depends on light.
What type of diode is a HVR-1X4 diode?
It's a high voltage diode, typically used in microwave ovens.
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.
What type of diode is used to convert alternating current into direct current?
The type of diode used to convert alternating current in to direct current is the power diode.
Explain how a general diode is used to change alternating current into direct current.?
The specific type of diode you are thinking of will only let current through in one direction.
Which type of machine maintains constant velocity and matches the resistance to the effort of the performer?
isomatic

What is blocking diode?
any diode if connected to where the anode is tie to a negative potential will block that voltage. Up to the limit of the breakdown potential of the diode whereby avalanche current will destroy the diode unless current limited

A tunnel diode, or Esaki diode, is a special type of diode that can operate very quickly using quantum tunneling, allowing it to work even with microwave frequencies (current switching direction billions of times per second).
What are the amount of voltage across the diode?
The amount of (forward biased) voltage across a diode is dependent on current and temperature. A typical silicon diode has a forward voltage of about 0.6V at low current and temperature. As current goes up, voltage goes up slightly, with a typical voltage being 1.4V at high current. As temperature goes up, voltage goes down slightly, but the maximum current rating also goes down.
When a diode is properly forward biased what is the voltage drop across it equal to?
The forward biased voltage drop of a diode depends on the type of diode and the current through the diode. A typical silicon diode will exhibit a voltage drop between 0.6v and 1.4v depending on current. An LED might range from 2v to 3v. A germanium diode might go a low as 0.2v. Bottom line; it varies.
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.
What happend when a diode is forward biased?
The diode conducts at its forward breakdown voltage. Depending on the current, and the type of diode, the voltage could be anywhere between 0.2 and 3.5 volts, with a nominal silicon range of 0.7 to 1.4.
How may type of resistors in diode?
None. A diode does not have a resistor in it. Diodes and resistors are different devices used for different purposes. For example, increasing current flow through a resistor increases the voltage drop across the resistor. Increasing current flow through a diode (within the diode's capabilities, just the same as a resistor) will actually decrease the voltage drop across the diode (once the diode "turns on" this voltage variance will be fairly small, though).
