Electronic Circuits and Diagram-Electronics Projects and Design

  Resistors Resistors are considered to be the most used and the most important component of all the electronic circuits. Take a look at the working, types and also use of resistors in the field of electronics. We know that the basic idea of any electronic circuit is the flow of electricity. This also is further categorized into two – conductors and insulators. Conductors allow the flow of electrons, while insulators do not. But the amount of electricity that we want to pass through them depends on the resistors. If a high voltage is passed through a conductor such as…

OLED Have you ever thought of having a high-definition TV that is bigger than your usual LCD display, and that consumes only half the power of an ordinary one? What if you could easily roll the TV and pack it up so that you can use it for a trip? Yes, this is possible with the organic Light Emitting Diode (OLED) technology. With such a component you can easily make PC monitors, high clarity cell-phone screens, watches and also indicators. They can also be used for illuminating a large area and is sure to replace the Liquid Crystal Display Technology…

Nowadays, people do not carry money for shopping. Instead, they carry an automated teller machine card, also known as ATM Card. When money is needed they go to the nearby ATM machine, insert their ATM card, and take the required amount. As these ATM machines are found in most of the supermarkets, towns, and even hotels. Do you have any idea how your bank money is received from any part of the country? In this post we will describe briefly on how the ATM is networked with the bank and the working of an ATM machine. Difference between ATM card…

Charge Coupled Device (CCD) – Definition CCD was developed in the year 1969 by Willard Boyle and George E. Smith at AT & T Bell Labs. It is a shift register device which can be used for the movement of electrical charge within the device. This movement can be from one area of the device to another and the digital value of the moved charge can be easily found out. When the signals are moved, one at a time from one place to another within the device, the value of the charge can be easily manipulated. There are capacitive bins…

Studies have shown that the past decade had a rise in the number of cars to almost 500% than the previous one! This rise in cars has also been a major cause for the vast environmental pollution throughout the world. The introduction of electric cars has proved that they are very much environmental friendly and less pollute compared to gas cars. There has been a rapid increase in the sale of electric cars for the past few years. Comparison between electric cars and gasoline cars An electric car is powered by an electric motor. But, a gasoline car is powered…

The bipolar junction transistor is the one which amplifies a small change in input current to produce a large change in output current. Another type of transistor, called a field effect transistor (FET), converts a change in input voltage into a change in output current and thus the gain of an FET is measured by its transconductance, defined as the ratio of change in output current to change in input voltage. The voltage is applied to the input terminal which is called its Gate and the current flowing through the transistor is depending on the electric field produced by the…

Nowadays desktop PC’s are getting diminished due to the high demand for laptops. Though both desktops and laptops have the same specifications, the way they are put together is what makes them different. You can carry your laptops wherever you like and can also be run on battery unlike a desktop computer (though it runs on UPS, it does not stand for a long time compared to laptop). They are smaller in size and also thin and lightweight. Desktop computers, on the other hand has bulky components and a lot of connectors. The screen and CPU has more weight and…

Working Of Inductors I have explained many articles on various electronic circuits, which shows applications of Inductors. But I have not explained the proper working of inductor till now. Inductors are used in many analog circuits and are also used along with capacitors for forming filter circuits and thus signal processing. They are also used in Switched Mode Power Supplies (SMPS), oscillators, transmitters, receivers, voltage regulators and also for over voltage protection. What is an Inductor? An Inductor, also known as a reactor is simply a coil of wire, which has many electrical properties when subjected to a magnetic field….

We always use devices made up of Liquid Crystal Displays (LCDs) like computers, digital watches and also DVD and CD players. They have become very common and have taken a giant leap in the screen industry by clearly replacing the use of Cathode Ray Tubes (CRT). CRT draws more power than LCD and are also bigger and heavier. All of us have seen an LCD, but no one knows the exact working of it. Let us take a look at the working of an LCD. The article below is developed as two sections:- 1. Basics of LCD Displays     2.  Working…

We have always shown keen interest in buying the best electronic stuffs like CD’s, tapes and also computers. No one has bothered much to know about the quality of the speakers that bring the ultimate output. Even if any high end amplifier and other devices are used, it will all become a waste if the proper loud speaker is not used to present the output. The speaker is mainly responsible for changing the electronic signals that are produced by the CD’s and other devices into audible sound. Sound To know more about the speaker, it is important that you know…
