Essays on Electricity

Electricity stages in Electricity distribution is the final stage in the delivery (before retail) of electricity to end users. A distribution system’s network carries electricity from the transmission system and delivers it to consumers. Typically, the network would include medium-voltage (less than 50 kV) power lines, electrical substations and pole-mounted transformers, low-voltage (less than 1…

Introduction This report has been requested as part of my 2nd Year HNC Beauty Therapy course. The purpose is to research and describe Electrotherapy Machines used within the beauty industry: High-frequency, Infra-red, Vacuum suction, G5, Galvanic, Faradic, and Paraffin wax. Each electrotherapy machine will be looked at: highlighting their advantages and disadvantages; the history behind…

Electricity generation is the process of creating electricity from other forms of energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire, or disc of copper…

A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. It divides a full rotation into a number of equal steps. A stepping motor is driven by a series of electrical pulses, which are generated by the MCU in an NC system. Each pulse causes the motor to rotate a…

In microwave and radio-frequency engineering, a stub is a length of transmission line or waveguide that is connected at one end only. The free end of the stub is either left open-circuit or (especially in the case of waveguides) short-circuited. Neglecting transmission line losses, the input impedance of the stub is purely reactive; either capacitive…

            At present, global energy issues will continue to pick up the pace, as the world as increases its consumption of the few non-renewable sources the planet has left. Currently, the price of oil in the world market has been hitting record highs of over $100 a barrel (The Independent). And the trend of increasing…

One of the greatest inventions that we use everyday in our lives, and cannot imagine life without it is the light bulb. Thomas Alva Edison invented the light bulb in the year 1879. With the advancement in technology, today we have different types of light bulbs such as Incandescent, Halogen, Fluorescent, Compact Fluorescent Lamps, High-Intensity…

Based on http://www.zamboanga.com, Caringo , Mercedes, Camarines Norte, Philippines is experiencing too many black outs, they also state that they don’t rely on Diesel fuel and coal for their Electricity, because in their place there are many renewable and sustainable source of energy like Hydro Power, Solar Power, and Wind Power. Background information: (Foreign) According…

Everyone knows who Thomas Edison is, and many attribute the “invention of electricity” to Edison, but this is simply not accurate. The truth is, while Thomas Edison did patent and market DC, or direct current, electricity, he did not “invent” electricity, and as a matter of fact, much of his work was actually basically stolen…

Ontario just like other developed parts of the world is faced with various environmental challenges which call for environmental protective measures. Environmental cleanliness has become an important issue in the whole world because of the adverse affects of global warming which have cost governments colossal amounts of monies to address. Partners for economic growth and…
