The passive two terminal electrical components that resist the flow of electrical current in an electrical network can be termed as Resistor. Resistors can be used for controlling or reducing the voltage levels within a circuit, and the voltage across an element in a circuit can be determined by the voltage drop across the resistor in parallel to that element. Resistors are of fixed or variable resistances, viz. photoresistor, humistors, varistors, trimmers, thermistors and potentiometers. Resistors are classified into different types based on different properties.

There are numerous important basic electrical components commonly found in the circuits of almost all peripherals. These devices are the essential building blocks of electronic and electrical circuits. These electric components can be found in great numbers on motherboards, video cards, hard disk, logic boards and everywhere else in personal computers. The electrical circuit components can be combined with each other and with dozens of other devices. [Read more…]
In recent years, wireless charging or inductive charging has become a desirable technology, as people are keen to avoid the mobile chargers and power cables to recharge their mobile phones, laptops, iPods and digital cameras. Fujistu laboratories limited has declared the expansion of wireless recharge technology that permits the design of wireless charging systems based on the magnetic resonance that can immediately recharge various types of portable electronic devices.

A location-based service (LBS) is a software application for a IP-capable mobile device that requires knowledge about where the mobile device is located. Location-based services play an important role in the future applications of satellite navigation. Location based services (LBS) are services offered through a mobile phone and take into account the device’s geographical location. [Read more…]
The execution of projects is an essential task for technical students as they pursue their studies. During the course of their engineering studies, projects help them to gain some practical knowledge from their studies. Many companies ask students about the projects they have developed to test their skills and knowledge. [Read more…]
Some critical applications need temporary hold off supply voltage for the backup supply kicks especially the applications like power meters, power electronic drives and industrial or home alarm systems. Therefore, the LTC 3355 voltage regulator IC supplies momentary uninterrupted power to the device from the energy stored in the capacitor and also it produces regulated power. It thus reduces the need to replace a battery and minimizes the maintenance of portable backup systems and low-cost applications. This article provides a brief description about this IC pin, its configuration and operation. [Read more…]
In this core competent world, one must equip or empower oneself with some specific skills and abilities to be independent and expert in a certain specified field. There is a significant difference between understanding a project by theory or flow of information and managing the project itself, but one should know the information before implementing the project. Therefore, practical knowledge is the most essential criterion for successful evaluation of the electronic projects. [Read more…]
The term wireless refers to the communication or transmission of information over a distance without requiring wires, cables or any other electrical conductors. Wireless communication is one of the important mediums of transmission of data or information to other devices. The Communication is set and the information is transmitted through the air, without requiring any cables, by using electromagnetic waves like radio frequencies, infrared, satellite, etc., in a wireless communication technology network.
In today’s world there are wide varieties of solid-state, switch-mode, power-supply transistors to perform switching operations in power-electronic systems. All these have their own specifications in terms of current, voltage, switching speed, load, driver circuitry and temperature. Each one has its limitations and advantages as well, but its usage depends on the requirements of the application. [Read more…]
