What is the aim of the PN junction diode experiment?
To calculate static and dynamic resistances of the Zener diode in both forward and reverse biased conditions (before, after break down voltages).
What precautions are to be taken when doing the experiment with a semiconductor diode?
Precautions:
- While doing the experiment do not exceed the readings of the diode. This may lead to damaging of the diode.
- Connect voltmeter and ammeter in correct polarities as shown in the circuit diagram.
- Do not switch ON the power supply unless you have checked the circuit connections as per the circuit diagram.
What are the two basic types of breadboards?
There are two major types of breadboards; these are solder and solderless boards. Solder boards are boards you have to solder components onto (per the name). These are most of your standard circuit boards, and if you flip one over you’ll notice that all of the connections are soldered to the board itself.
Where do we use diode?
Despite being nothing more than a simple two-pin semiconductor devices, diodes are vital to modern electronics. Some of their most common applications include turning AC to DC, isolating signals from a supply, and mixing signals. A diode has two ‘sides’ and each side is doped differently.
What are the advantage and application of PN junction and Zener diode?
Zener Diode: Basic Operations and Applications Zener diodes operate the same as a PN junction diode when in the forward-bias direction, but it’s typically used for the reverse mode in its applications. That said, zener diodes also regulate voltage one way (regular) or both ways (bidirectional).
What is the aim of diode?
The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking it in the opposite direction (the reverse direction).
What happens if Zener diode is forward biased?
The Zener diode operates just like the normal diode when in the forward-bias mode, and has a turn-on voltage of between 0.3 and 0.7 V. As the reverse voltage increases to the predetermined breakdown voltage (Vz), a current starts flowing through the diode.
What is the need for connecting resistance Rs in series with PN diode?
A diode is connected in series with a resistor because a diode essentially acts like a short while forward biased and a open when reverse biased, when a diode is forward biased its resistance is very very low so it will produce a very high circuit current if a resistor is not added in series to increase the total …
Why do they call it a breadboard?
The term breadboard comes from the early days of electronics, when people would literally drive nails or screws into wooden boards on which they cut bread in order to connect their circuits.
