Amplifier Definition and explanation with Diagram

The amplifier is one of the devices in electronics that are used in majorly every device. It is mainly used in devices that deal with signal strength like audio, power, etc. According to the output signal, it is categorized into 3 categories. In this article, we are going to discuss the definition, working, diagram, gain, efficiency, classification, etc in detail. Amplifier Definition An amplifier is an electronic circuit used to boost up the strength of the weak signal. This signal can be a current, voltage or power. It is a 2 port circuit that increases the amplitude of the input signal …

Resistor Symbol, working, Color code and Types

by Ajay Kumar

The resistor is an electronic component restricts or limit the flow of current and divides the voltage in an electronic circuit. It is one of the most important passive components of an electronic industry because, without these components, active devices cannot process the electrical signals. Its main purpose is to provide a precise quantity of electrical resistance. In our previous articles, we explain, capacitors, types of capacitors, diodes in detail. In this article, we are going to explain resistors, resistor colour coding , types of resistors in detail. Resistors Basics: Resistors mainly added to those circuits where they complement the …

Bridge Rectifier Circuit, Operation, Characteristics & Advantages

by Ajay Kumar

Full wave bridge rectifier is another type of full wave rectifier used to convert an alternating current input into a direct current output. In a bridge circuit configuration, it comprises of four diodes that provide the same polarity of output for either polarity of the input. The main feature of this diode bridge which makes it more efficient than centre tap rectifier is its polarity i.e. the polarity of output is same as that of input. In our previous articles, we explain rectifier, half wave rectifier, Efficiency equation of half wave rectifier, efficiency equation of full wave rectifier etc. In …

Full wave Rectifier Efficiency Equation and Applications

by Ajay Kumar

Full wave rectifier basically uses both half cycles of the applied AC voltage and converts an AC voltage into a pulsating DC voltage. In full wave rectification, one diode conducts during one half-cycle while other conducts during the other half cycle of the applied AC voltage. It has some advantages over half wave rectifier like it has high average output DC voltage and has much fewer ripples resulting in the smoother output waveform. In our previous article, we explain Rectifier, half wave rectifier efficiency, diodes, p-n junction etc in detail. In this article, we are going to explain the mathematical …

Full Wave Rectifier Circuit, Characteristics, Advantages & Disadvantages

by Ajay Kumar

In this chapter, we are going to learn about second type of rectifier that is full wave rectifier. Unlike half wave, full wave rectifier is mostly used. We have already discussed rectifier and half wave rectifier in our previous tutorials. From them, we got to know that there is a vast difference between the characteristics and efficiency of different rectifiers. Now we will learn the types and characteristics of full wave rectifier. Full Wave Rectifier Full wave rectifier can be defined as “a type of rectifier that converts the alternating voltage into pulsating direct voltage but unlike half wave rectifier, …

Half Wave Rectifier Efficiency Equation and Applications

by Ajay Kumar

This is third chapter in Rectifier series. In the last two chapters we have covered the basics of rectifiers, and Half wave rectifier. Though we have covered various properties in our last article but kept aside a mathematical derivation of half wave rectifier efficiency equation. Because we think it needs to be explained separately. In this article, we are going to learn to calculate the equation of efficiency of half wave rectifier and about its various applications in detail. Before learning ahead, let’s have a little recap about the working of a half-wave rectifier. In Half wave rectifier, the diode …

Half wave Rectifier Circuit, working, operation and characteristics

by Ajay Kumar

We have covered the basics of Rectifier and its types in our previous article. Now we will learn about each type of rectifier individually. In this article, we will cover all about half wave rectifier. As we have read that there are mainly three types of rectifiers, namely half wave, full wave, and center tapped. This classification is done keeping in mind whether it uses full AC voltage waveform or half. Keep this point in mind while going through the rest of the article. What is Half Wave Rectifier? Half Wave Rectifier Definition can be given as: A Half wave …

Rectifiers Basics, Types and Comparison

by Ajay Kumar

A rectifier or AC to DC Converter is one of the most important devices when we talk about Electricity. It is used to convert one form of the current into another. And because of it, we have electricity in our house. So, in this chapter, we will cover rectifier definition, uses, the process of rectification, circuit and types. What is a Rectifier A rectifier is an electrical device that consists of one or more diodes allowing the flow of current only in one direction. It basically converts an alternating current into direct current. The process of converting Alternating Current into …

Tunnel Diode And Tunnelling Effect

by Ajay Kumar

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 a Tunnel Diode? A Tunnel diode is a p-n junction device which exhibits negative resistance. With Negative resistance, we mean “By Increasing the voltage the current through it decreased“. It is also known as Esaki diodes named after Leo Esaki. He received the Nobel Prize …

Schottky Diode working, construction, characteristics and Applications

by Ajay Kumar

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 are going to explain Schottky diode operation, construction and factors etc in detail. It was named after German Physicist Walter H. Schottky, the barrier means the potential energy barrier for the electrons at the junction. This diode has a low forward voltage drop usually between …
