The National Electrical Code® (NEC®) was developed over a century ago during a vibrant and exciting time in American history. In the decades following the Civil War‚ an industrial revolution arises in the United States fueled by the technological advancements in electricity. In September of 1882‚ Thomas Edison installs the first commercial electrical system at Pearl Street Station in Lower Manhattan. Within a few short years‚ electrical light and power spreads from city to city and from industrial

lives or cause any suffering. The purpose of the essay is to explore the specific issues that face electrical engineers. The primary focus in this essay will be addressing the question: how can an issue be an ethical concern if it does not directly endanger human life or society? This is particularly important as in contrast to other branches of engineering‚ the moral issues surrounding electrical engineering do not usually affect a consumer’s health or lead to injury or death. A civil engineering

network for supplying this electrical power is known commonly as the National Grid. The National Grid is an electric power transmission network which connects the substations and power stations. This is so that any electrical energy generated in Great Britain‚ can be utilized and help meet energy demands elsewhere. This grid system also includes interconnections that run under the sea to Northern Ireland HVDC Moyle‚ the Isle of Man and France HVDC Cross-Channel. The electrical energy generated for the

Electrical Conductance and Insulation OVERVIEW: Every thing in the world is differentiable on the basis of its electrical conductance. Some things are called insulators and these substances never conduct electricity. they include things such as cold air‚wood and plastic. Then there are things that conduct electricity and current flows through them‚ they are called conductors. examples of conductors are most metals like copper and steel. Other materials that are sometimes used as conductors are

Resistors & Ohm’s Law Abstract: In this lab‚ students were introduced to the field of electrical engineering. The objectives of the lab were to determine the resistance of a resistor using various methods and to also verify Ohm’s Law. In the lab‚ the students were instructed to calculate the resistance by using color codes‚ measuring the resistance using a Digital Multi Meter‚ calculate the average resistance from 10 voltage and current measurements‚ and find the graphical resistance

Refractive index measurement is actually a measurement of the speed of light in a medium. The speed of light (usually denoted by c) is 299 792 458 m/s in vacuum. In other media the speed of light is lower than this value‚ and the refractive index‚ R.I.‚ of a medium is a measure of how much the speed of light is reduced in the medium. The refractive index (n) of a medium is defined as the ratio of speed of light in vacuum (c) in to that in the medium (v) The speed of light in a medium depends on
