LED or Light Emitting Diodes: Definitive Basic Guide

LED or Light Emitting Diodes: Definitive Basic Guide

Ever seen small bulbs probably in size of a millimeter that we mostly use in decorating our house, shop, etc in Christmas, New Year, Diwali, or any other occasion? They are LED Bulbs. Though very tiny but they glow brightly in the dark. Some of them just glow constantly, and some of them switch their…

Gunn Diode Explaination

What is a Gunn diode A Gunn Diode is a microwave semiconductor diode designed to work in devices having microwave frequencies. Microwave Frequencies are electromagnetic radiation of tremendously high frequencies (THF), (maximum working frequency up to 3 THz, this depends on the material used in its structure). The most common materials used in their manufacturing…

Tunnel Diode And Tunnelling Effect

Tunnel Diode And Tunnelling Effect

Every student faces difficulty understanding the concept of Tunneling effect in the tunnel diode. Students are much confused about different types of diodes they encounter in their academics. We have already explained Photodiodes, Zener diode, Schottky Diode, LED etc. Now, we are going to explain about Tunnel diode, working operation, construction, and applications etc. What is…

Schottky Diode working, construction, characteristics and Applications

Schottky Diode working, construction, characteristics and Applications

Schottky diode is also known as the hot carrier diode is made up of semiconductor-metal junction rather than a p-n semiconductor junction. It is widely used for radio frequency, RF applications as a mixer or detector diode. In our previous articles, we explain about Zener Diode, Light emitting diode, Photodiode etc. In this article, we…

Diode: Types, operation and Symbols [Guide]

Diode: Types, operation and Symbols [Guide]

Diode is an electronic device conduct current in one direction i.e. either in the forward direction or in the reverse direction. Today’s most commonly used diode is semiconductor diode. In our previous articles, we explain basic theory of semiconductors, P-n junction diode, and P-n junction diode characteristics etc. Here we are going to explain about Diodes…

PN junction Diode Characteristics and Biasing

PN junction Diode Characteristics and Biasing

Pn junction diode is one of the most basic diodes. It is used in the construction of transistors, FET, Gates and many other types of integrated circuits. These are the easiest and basic diodes available in and use PN junction characteristics like depletion layer, diffusion and drift current. We prefer to read our article on PN…

Electrical and Electronics Symbols

Electrical and Electronics Symbols

We all know how much we struggle to read wiring diagrams properly. And I know you are completely at the “no-fault zone” with this. With many electrical symbols, it is very difficult to remember every one of them and using them while solving a circuit diagram. But there is an easy way to remember them….
