Current is produced in a conductor when it is moved through a magnetic field because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. This process of generating current in a conductor by placing the conductor in a changing magnetic field is called…

My life’s goal has never been to live solely for survival; I have always aimed to maximize my life’s potential. This desire for complete satisfaction with my work motivated me to enroll in a prestigious University. Upon completing my post-graduation, I intend to pursue a career that integrates Electrical and Software knowledge, thereby enhancing my…

There are numerous ways electricity is employed in the operating room environment, such as X-ray machines, electrosurgical units, monitors, surgical table and lights, endoscopic cameras and monitors, lasers, and robotics. Each piece of machinery comes with certain safety precautions when using them in the perioperative environment. Since almost all injuries in the OR result in…

In its most basic definition. an electric generator is a machine that produces electricity. Generators produce about all of the electricity used by people. They supply the electric power that runs machines in mills. supply illuming. and operate contraptions in the place. There are two chief types of generators – alternating-current ( AC ) generators…

Abstract Electrical cables are the major arteries for electrical power. The power utilities are facing new challenges due to liberalization of electricity. It means reliability demand on distribution network is increasing day by day. The distribution networks are mainly cable networks of different voltage grade and dielectrics. Therefore, the proof design of cables is required…

What provision must be made for short-circuit conditions in motor circuits? Circuit-breaker or fuse protection of sufficient breaking capacity to deal with any possible short-circuit that may occur must be provided, since overload relays are not designed to operate and clear the circuit in the event of a short-circuit. What are the usual forms of…

I have selected Ceylon Electricity Board ( CEB ) , one of the chief participants in the energy sector of Sri Lankan economic system ( I have experienced working with them ) , to measure the cultural influences to employee motive scheme of the entity. CEB, which is a 100 % province owned endeavor, has…

A wire-map tester consists of a remote unit that you attach to the far end of a connection and the battery-operated, handheld main unit that displays the results. Typically, the tester displays various codes o describe the type of faults it finds, so you know which part of the cable you messed up on or…

Power Systems of today are very large, complex interconnected network of various components. Major components of a power system can be subdivided into: a. Generation b. Transmission and Sub transmission c. Distribution Conventional ac electric power systems are designed to operate with sinusoidal voltages and currents. However, nonlinear and electronically switched loads distort steady state…

VAN DE GRAAFF GENERATOR This is a machine that can build up high voltages of the order of a few million volts. The resulting large electric fields are used to accelerate charged particles (electrons, protons, ions) to high energies needed for experiments to probe the small scale structure of matter. Principle 1. Skin effect 2….
