How does pn junction applied in electronic devices?
The process of applying the external voltage to a p-n junction semiconductor diode is called biasing. External voltage to the p-n junction diode is applied in any of the two methods: forward biasing or reverse biasing. If the p-n junction diode is forward biased, it allows the electric current flow.
What is the result of PN junction diode experiment?
Result: The V-I characteristic of PN junction diode indicates that the forward current is negligible up to the knee voltage. After that it increases appreciably. The knee voltage for diode is 0.7 volt.
What is PN junction diode PDF?
A p-n junction is an interface or a boundary between two semiconductor material types, namely the p-type and the n-type, inside a semiconductor. The p-side or the positive side of the semiconductor has an excess of holes and the n-side or the negative side has an excess of electrons.
What is a breadboard used for in electronics?
A breadboard allows for easy and quick creation of temporary electronic circuits or to carry out experiments with circuit design. Breadboards enable developers to easily connect components or wires thanks to the rows and columns of internally connected spring clips underneath the perforated plastic enclosure.
Which is an example of pn junction diode?
P-N junction diode can be used as a photodiode as the diode is sensitive to the light when the configuration of the diode is reverse-biased. It can be used as a solar cell….Applications of P-N Junction Diode.

What are the applications of pn junction diode?
Applications of PN Junction Diode It can be used as a solar cell. When the diode is forward-biased, it can be used in LED lighting applications. It is used as rectifiers in many electric circuits and as a voltage- controlled oscillator in varactors.
What is pn junction diode in electronics?
A PN Junction Diode is one of the simplest semiconductor devices around, and which has the electrical characteristic of passing current through itself in one direction only. However, unlike a resistor, a diode does not behave linearly with respect to the applied voltage.
What is the conclusion of diode?
CONCLUSION part A From that experiment we can conclude the diode can change the AC input to the DC output. Because the diode just allows current flow to it just in one direction only.
What is pn junction diode explain its working?
A diode (PN junction) in an electrical circuit allows current to flow more easily in one direction than another. Forward biasing means putting a voltage across a diode that allows current to flow easily, while reverse biasing means putting a voltage across a diode in the opposite direction.
Why we use pn junction diode?
A p-n junction diode allows electric current when it is forward biased and blocks electric current when it is reverse biased. This action of p-n junction diode enables us to use it as a rectifier.
How is breadboard connected?
The holes in a breadboard are connected by metal clips that span five holes, horizontally. These metal clips allow each row of five holes to be connected. There are no vertical connections on a terminal strip. Horizontal rows on either side of the center groove are also not connected to each other.
What is application of breadboard?
The main application of a breadboard is to form simple electrical connections among different components so that you can check your circuit before soldering it to the board. These boards allow different components to be simply placed or removed or the term prototyping instantly comes to mind permanently.
