by Tarun Agarwal 11 years ago Opto Couplers – Types & Applications Opto-isolators or Opto-couplers, are made up of a light emitting device, and a light sensitive device, all wrapped up in one package, but with no electrical connection between the two, just a beam of light. The light emitter is nearly always...
by Tarun Agarwal 11 years ago Fluorescent Lamps – Definition, Working & Application What are Fluorescent lamps? Fluorescent lamps are lamps in which light is produced as a result of flow of free electrons and ions inside a gas. A typical Fluorescent lamp consists of a glass tube coated with phosphor and containing a pair...
by Tarun Agarwal 11 years ago 3 Different Types of Displays Available Display devices are the output devices for presentation of information in text or image form. An output device is a thing that provides a way to show information to the outside world. For displaying the information in an appropriate manner...
by Tarun Agarwal 11 years ago Different Ways to Control Car Parking Parking a car can be a troublesome task in many public places like malls, exhibitions etc. Car parking lots in buildings are usually managed manually on the space available. Moreover managing the whole parking system manually is quite...
by Tarun Agarwal 11 years ago Pulse Width Modulation (PWM) Use of PWM as a switching technique Pulse Width Modulation (PWM) is a commonly used technique for generally controlling DC power to an electrical device, made practical by modern electronic power switches. However it also finds its place...
by Tarun Agarwal 11 years ago What is an IC 4017 : Pin Configuration & Its Application Most of us are more comfortable with 1, 2, 3, 4… rather than 001, 010, 011, 100. We mean to say that we will need a decimal coded output in many cases rather than a raw binary output. We have many counter ICs available but most of them...
by Tarun Agarwal 11 years ago What is a TRIAC : Working & Its Applications We know that the unidirectional device like an SCR includes the characteristics of the reverse blocking current because it stops the flow of current in a reverse-biased state however for several applications, this kind of current control...
by Tarun Agarwal 11 years ago LED Light Sources 3 Reasons why are LEDs being used as a source of light compared to HID lamps LEDs don’t have a filament to burn out or break; therefore, they last much longer than conventional bulbs. Given that a very small semiconductor chip runs an...
by Tarun Agarwal 11 years ago Mains Operated LED Introduction to LED An LED or Light Emitting Diode is a simple PN junction diode, made of material with larger energy barrier. As the supply is given to the LED junction, the electrons move from the valence band to the conduction band....
by Tarun Agarwal 11 years ago Cycloconverters – Types & Applications In industrial applications, two forms of electrical energy Direct Current (DC) and Alternate current (AC) are used. Constant voltage and constant current AC is directly available. However, for different applications, different forms, different...
