Why do we choose LED Light Bars? A Led lights are a short either long bunch of huge-brightness Led lights. They give a luminous, extensive and forcing pole of light ahead, behind or to the side. They feed a powerful profit for dark driving or...

Hydroelectric power is a kind of renewable energy and have a very old history. The world first hydroelectric power plant has been exist and began operated at September 30, 1882 on the fox river in Appleton, Wisconsin. The electricity that generate in the world got...

Lightning or illumination: Lighting or illumination is the purposeful use of light to achieve a practical or visual effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting is sometimes used...

Electrical resistivity is a fundamental property that quantifies how strongly a given material opposes. Resistivity is measured by ohmsO. Electrons often encounter semi or non-conductive materials which causes resistance. A low resistivity indicates a material that readily allows the flow of electric current. Electrical conductivity...

Thyristor is a type of diode that allows current to flow if and only if a control voltage is applied to its gate terminal. This kind of diode has three electrodes namely anode, cathode and gate. Thyristors have different working principle depending on its classification....

A diode is an electronic component allows current to flow easily in one direction but blocks current in the other direction. Most diodes are made from a silicon semi-conductor material. To make silicon a more effective semi-conductor the material goes through a process called doping....

An Aircraft Electrical System is a self contained network of components that generate, transmit, distribute, utilize and store electrical energy. General Description An electrical system is an integratal and essential component of all but the most simplistic of aircraft designs. The electical system capacity and...

Magnetism produces lines of force known as flux. These can be detected by compass needle which shows the direction you are travelling as the earth’s magnetic north pole attracts the north ends of other magnets. The magnetic lines of force start from the north pole...

To understand electricity, we must understand what causes the electricity to flow. Electricity is a form of energy. All matter is made up of atoms and atoms have sub-atomic particles. There are three sub-atomic particles, which are protons, neutrons and electrons. The structure is so...

There are many incidents that occurred in the United States, which led to disastrous consequences. The Rodney King’s case and the New York blackout in 1977 are two incidents that have had catastrophic consequences. There are also many things everyone can learn from reading or...

Light and materials are inseparably connected; indeed they actually determine each other: neither is visible to the human eye until the two come together. Light and materials are mutually dependent on each other. Materials are key to understanding light in architecture because they directly affect...

Global lithium-ion battery market is projected to cross more than US$ 40 Billion by the end of year 2024. As we discuss about Lithium-ion batteries, it is a favored source of portable electronics. A lot of research and development is doing by the Battery manufacturer...

At this moment in time, with electricity demand around the world continuing to increase, one way we might reduce our reliance on non-renewable energies is to start using renewables, such as wind energy. Wind energy is set to have an increasingly significant part in the...

The imminent need for energy sources in human history takes us to analyse the history and potential of a well know market, the industry of batteries. When we think of batteries we not only reach the thought of an energy source, but we also must...

I’ve been really interested in renewable and sustainable energy sources for a while. While there are many sustainable, renewable energy sources that can be used on a large scale and sold to consumers, I will discuss smaller scale systems that can be implemented within an...

Abstract: This paper simulates the mathematical model of the PV (photovoltaic) module based on the MATLAB script file with all the parameters are involved. Modeling this device environmental factors such as irradiation and temperature needs as input variables. The output of the PV module varies...

Abstract— Frequency selective surface (FSS) is a repeated structure is transmitting, reflecting or absorbing based up on the mode of interest by using patches or slots. The patch and slot arrays effectively create band stop and band pass filters. The FSS have potential applications in...

Protection system is an integral part of an electrical transmission systems. Previously, various protection methods has been proposed for AC systems and has been hammered for years to get a better performance. In the last few decades, HVDC transmission has been introduced as a solution...

FUNDAMENTAL ASPECT OF SUPERCAPACITOR: Source of energy and environmental issues are the reason for development of renewable energy storage system. One of the them is supercapacitors called as ultra-capacitor and electrical double layer capacitor (EDLC). Supercapacitor store energy in the form of electric field, which...

Abstract The proposed work in this paper describes about the electromagnetic design, simulation and fabrication of a multilayer carbon materials based radar absorbing structural (RAS) composite working for X band application. The RAS laminates have been fabricated using the lossy carbon materials in the epoxy...

Living in a house, self-owned or rented, the issue of maintenance regarding, plumbers, electricians, carpenters, door lock and key repair, painters are definitely going to crop up from time to time. Regarding Electrician in Grange in the case of a self-owned house, the owner is...

Introduction Electric energy is moved from generating site ( source where it is converted from other form of energy) to load (where it will be used ) through high voltage transmission lines. High voltage is used to reduce energy loss, however it produces strong electric...
