Transistor Circuit Design
Mar 8th
Transistors are inevitable parts of Electronic circuits. The success of a circuit design lies in the selection of proper transistor type and calculation of voltage and current flowing through it. A small variation in the voltage or current level in the transitor will affects the working of the whole circuit. Here explains how a transistor works.
Voltage and Current Divider
Mar 6th
Voltage and Current divider arrangements are the common in electronic circuits. Before selecting the value of resistors, it is necessary to calculate the voltage and current from the output of a resistor chain. So that the circuit will function properly. Here is a simple but useful tip to calculate the voltage and current from resistor chains.
Cell Phone Misuse. Some facts
Mar 4th
See how an excellent electronic device is misusing when it is popular. There is no electronics content in this article, still it is related to an electronic device. Mobile Phone is a Real Friend but ……. inconsiderate, annoying, discourteous in public places if it is misused. (more…)
Mobile Phone. How it works?
Mar 2nd
A mobile phone is an electronic device used for mobile telecommunications over a cellular network of specialized base stations known as cell sites. A cell phone offers full Duplex Communication and transfer the link when the user moves from one cell to another. As the phone user moves from one cell area to another, the system automatically commands the mobile phone and a cell site with a stronger signal, to switch on to a new frequency in order to keep the link.

Metal Oxide Varistor
Feb 28th
The Metal Oxide Varistor or MOV is a voltage dependent, nonlinear device that provides excellent transient voltage suppression. The Metal Oxide Varistor is designed to protect various types of electronic devices and semiconductor elements from switching and induced lightning surges.
When exposed to high transient voltage, the MOV clamps voltage to a safe level. A metal oxide varistor absorbs potentially destructive energy and dissipates it as heat, thus protecting vulnerable circuit components and preventing system damage. Varistors can absorb part of a surge. (more…)
