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 state On/Off and vice-versa. I hope you have got an idea of what we are going to discuss in this article. If not, see the image below for better understanding. Yes, we are going to learn about Light Emitting diodes and LED lights their working, …

Different Types of Electrical Panels and their benefits

by Ajay Kumar

Electrical panels are the home to electrical housing and electrical components. They are useful towards securing all the electrical components and provides for cost-effective reliability as well. They also provide for a well classified and neatly categorized substation from where you can control the functioning of many of the electrical components and circuits. Electrical panels can vary in their strength and size and may take the form of main breaker panel, the main lug panel and the sub panel. The electrical panel is also the place where the different breaker components and switches are located. The new building electric codes …

Wheel locks: What are they and how they work

by Ajay Kumar

What Are Wheel Locks? Before we discuss how wheel locks work, let’s define what they are. These devices are installed instead of the lug nuts. They cannot be removed by anything but the particular key in the set. The type of wheel lock is different according to the wheel style. But how do they work? It is a common question to those who have encountered the term wheel locks for their custom rims and wheels. For one, these locks work to protect your flashy custom rims against thieves or people who do not buy their own. These rims are incredible …

Common types of soldering iron and how to choose them

by Ajay Kumar

What is a Soldering iron? A soldering iron is a handy tool that can be used for soldering at home or commercial facilities. The tool has a metallic tip with insulated handle attached to it. When giving current , the metallic tip provides heat to the solder. The solder is a metal allow that fuses into the gap between 2 metals needed to be join. By heating solder, it melts and fuses between the metals joining them permanently. Depending on the requirement, there are many different types of irons to choose from. The type of soldering projects you commonly do …

Gunn Diode Explaination

by Ajay Kumar

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 process are GaAs (Gallium Arsenide), and GaN (Gallium Nitride). In that process, microwave diodes require a unique environment (from lead due to sensitivity to electromagnetic pulses). The symbol of this diode is as shown below: Gunn diodes have short switching times due to their design. …

electrical symbols of different components

Electrical and Electronics Symbols

by Ajay Kumar

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. And believe me when I say its easy. With my graduation in electronics, I have used this trick and was able to solve many circuit diagrams. The trick is: Learn to read electronic symbols. And these symbols are useful also if you are from the …

Push Pull Amplifier Circuit, Operation, Advantages and Disadvantages

by Ajay Kumar

In our previous article, we have introduced you to amplifiers and its types. To recall it again, “An amplifier is an electronic device used to boost up the strength of the weak signal.” For full knowledge go through this tutorial of amplifiers. In our previous articles, we explained power amplifier, Amplifier classes, Class A power amplifier theory etc in detail. Here in this article, we are going to explore about Push-Pull Amplifier, its circuit, operation, advantages, and disadvantages in detail. What is a Push-Pull Amplifier? A push-pull amplifier is a type of amplifier that can drive current in either direction through the load. …

Class A Power Amplifier Circuit: Efficiency | Characteristics Guide

by Ajay Kumar

In electronics, power amplifiers are categorized into various classes. These classes are based on the different characteristics of different power amplifier circuits. And Class A Amplifier is one of the simplest types of power amplifiers. Though it is least used power amplifier, it is one of the most asked amplifier class in interviews and various competitive exams. I have received many comments from our readers to write on this topic. So I decided to gather all of the knowledge I can and explain it in easiest way to my readers. Here we are going to explain the efficiency equation, advantages, …

Power Amplifier Circuit, Classes and its Characteristics

by Ajay Kumar

A Power amplifier is a type of amplifier used to increase the amplitude of the signal and makes it stronger than the given input signal. It is the most demandable electronic device in the eyes of professionals because it comes in various forms and used in several circuits. The main operating characteristics of an ideal amplifier is power output, signal gain, efficiency, and linearity but normally there is always remain some trade-off between these characteristics. As we know not all amplifiers provide an accurate output, and there is always cost factor to consider. In our previous article, we explain power …

What is Power Amplifier: Properties and Classifications

by Ajay Kumar

Many times, we are not able to hear the voice coming out of the loudspeaker. It mainly happens when there is a large gathering. That means the voice coming out of loudspeakers is not audible to a big area. For this purpose, we need to raise the strength of the signal. This process of increasing power or strength of the signal so that it can be heard by the crowd is called Amplification. And the electronic device used for this purpose is a Power Amplifier. What is a Power Amplifier A Power amplifier is defined as an electronic device that provides …
