by Tarun Agarwal 12 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 12 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 12 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 12 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...
by Tarun Agarwal 12 years ago Servo Motor – Working, Advantages & Disadvantages Servo implies an error sensing feedback control which is utilized to correct the performance of a system. It also requires a generally sophisticated controller, often a dedicated module designed particularly for use with servomotors. Servo...
by Tarun Agarwal 12 years ago RFID Tags & Applications What is an RFID tag? The RFID tag is a microchip with an antenna in a compact package. The Tag can be attached to the object to be tracked through Radiofrequency. The Tag’s antenna picks up the signals from the RFID reader and then returns...
by Tarun Agarwal 12 years ago Temperature Controller Temperature is the most often measured environmental quantity and many biological, chemical, physical, mechanical and electronic systems are affected by temperature. Some processes work well only within a narrow range of temperatures. So...
by Tarun Agarwal 12 years ago Brushless DC Motor – Advantages, Applications & Control Definition A brushless DC motor consists of a rotor in the form of a permanent magnet and stator in the form of polyphase armature windings. It differs from the conventional dc motor in such that it doesn’t contain brushes and the commutation...
by Tarun Agarwal 12 years ago Temperature Sensors – Types, Working & Operation Temperature is the most often-measured environmental quantity. This might be expected since most physical, electronic, chemical, mechanical, and biological systems are affected by temperature. Certain chemical reactions, biological processes,...
by Tarun Agarwal 12 years ago What is a Stepper Motor : Types & Its Working A stepper motor is an electromechanical device it converts electrical power into mechanical power. Also, it is a brushless, synchronous electric motor that can divide a full rotation into an expansive number of steps. The motor’s...
