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 occasions? They are LEDs. 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 what we are going to discuss in this article. If not, see the image below for better understanding. Yes, we are going to learn what Light Emitting diodes are, their working and how they are …

Class A Power Amplifier Theory, Efficiency equation, Advantages and Disadvantages

Class A power amplifier is one of the simplest types of power amplifier have high fidelity and totally immune to crossover distortion. In the standard common emitter circuit configuration, class A amplifier uses the switching transistor.  The transistor is always turned ON so that the output current flows for the entire cycle of the input waveform. To control the high load current, class A amplifier may use a single power transistor or a pair of a transistor connected together. In our previous article, we explain power amplifier circuit,  semiconductors, diodes, rectifiers in detail. Here we are going to explain Class A …

Power Amplifier Circuit, Classes and its Characteristics

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 professional because it comes in various forms and used in a number of 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 …

Power Amplifier Definition, Properties and Classifications

A Power amplifier is an electronic device which provides sufficient power to an output load to drive a speaker or other power device, typically a few watts to tens of watts. The main purpose of this amplifier is to raise the power level of the input signal, to get the large power at the output. To match the input signal shape with larger amplitude, power amplifier takes the energy from the power supply & controls the output. In our previous article, we explain Amplifiers, Transistors, diodes, rectifiers in detail. In this article, we are going to explain Power amplifier working, performance …

Resistor Symbol, working, Color code and Types

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 image

Bridge Rectifier Circuit, Operation, Characteristics & Advantages

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 …
