Electricity is a form of energy, a result of the existence of electrical charge. Its theory and inseparable effect is probably the most accurate and complete of all scientific theories. Because of it, invention of motors, generators, telephones, radio and television, medical gadgets, computers and nuclear-energy systems have taken place. However, the many terms and definitions of electricity make it quite hard to pick up by students. So here's an outline that can be used by anyone who might have a hard time lecturing about it.
1.
What do a TV picture and lightning have in common? They are caused by tiny electrically charged particle called electrons. This flow or movement of electrons is what we call as electricity. Electrical charges cause television sets to work and telephones to ring.
2. What is static electricity? All matter is made of atoms and tiny particles held together by electric forces. Inside each atom are positively charged protons and negatively charged electrons.
They are attracted to each other. A buildup of positive or negative charges is known as static electricity. Example: When you brush your hair on a dry day, you may see sparks or hear a breaking sound. This happens because when you brush, many free electrons gather in your hair. Your brush does not have as many negative charges, so the charges from your hair get transferred to the brush.
3.
What are conductors? They are what carry electric charges. Most conductors have many free electrons. A metal doorknob is an example of a conductor. Objects that generally do not conduct charges are called insulators.
During a thunderstorm in 1752, Benjamin Franklin flew a kite that had a metal tip connected to a silk string that acted as a conductor. A key was then attached to the string at a point near the ground.
When Franklin touched the key it sparked and he could feel the electricity. Note that the next two who tried this extremely dangerous experiment were killed.
There is also a massive buildup of electrons in a cloud. You see lightning when the electrons are finally discharged or released to the ground.
4. Where does electrical energy come from? When you plug in an electric fan, you are not really using electricity. Instead you are using electric power.
The source of this power is a generator. Large generators supply huge quantities of electric power to your community.
When teaching, your goals must be straight cut. Create an outline if you have to. It gives you a general flow of what you want to teach and allows you to check loopholes along the way. To prevent misunderstandings between you and your students, ask questions as well.
As teachers, your role is to ensure you are effectively feeding the right information to your students..

Temple, PA (ContentDesk) September 11, 2005 -- eCycle announced today that it will be exhibiting at the 1st annual PA Energy Fest located in Kempton, PA on September 23-24, 2005.
The event will focus on renewable energy and sustainable living. Attendees will have a chance to see the new line of eCycle's Auxiliary Power Units (APU) and DC Generators.
The APU was designed to answer market demand for lightweight, high efficiency mobile DC power solutions in compliance with anti-idling laws that are being mandated throughout Canada and the United States.
These units are ideal for vehicles requiring DC power as part of a total generation system.
Depending on the application, the units can be configured to produce up to 6kW at low voltage (14, 28 or 72VDC) with current up to 400A.Recreational vehicles, residential and small business power back-up, including in conjunction with solar, wind and hydropower, will benefit from the eCycle APU.

A New Paradigm for the Indian power sector
Ever since India got independence in 1947, there has been a substantial growth in India's electric power sector. This sector has been growing at a CAGR of 8.2%. In spite of this growth, per capita power consumption is still low as compared to the average consumption worldwide.
Also various government agencies & organizations have been regulating and controlling the Power sector in India. On the other hand, only limited areas of jurisdiction & consumer base are covered by the private sector.
Following the trends in other parts of the world, Indian power sector is also undergoing a process of restructuring and reformation.
Independent regulatory commissions are being set up & vertical integrated utilities are being unrolled in to corporate entities. Various efforts are being put in for facilitating competition, wherever possible, in this sector.
Also, new institutional entities were set up in power sector. Healthy relationship amongst...
eCycle, Inc. Announces its Lightest 11kW B Brushless Motor - Enables Many Aerospace Applications
Temple, PA (ContentDesk) January 2, 2006 -- eCycle recently announced its newest brushless motor designed for aerospace applications.
Based on the CMG Silicon Series brushless motor generator, the EA Series (eCycle Aerospace) brushless motor weighs only 10.5lbs and produces 11kW at 6,500rpm.
The EA brushless motor was originally developed for an unmanned aerial vehicle (UAV) to enable vertical take off and landing (VTOL) operations.
The EA brushless motor shares many of the same features found in the standard CMG Silicon Series that weighs 15lbs.
By utilizing a custom housing and end bells, in conjunction with a lightened rotor and titanium shaft, the company was able to remove more than 4lbs.
from the standard motor.
Both the EA Series and CMG Silicon Series brushless motors operate at low voltage (12 -72VDC) and high current (up to 450 A).According to Dan Sodomsky, eCycles President and CEO, EA brushless motors will raise industry...
SEO Inc. Offers XML Sitemap Generator for Google Sitemaps
(ContentDesk) June 28, 2005 -- Google recently launched a service that allows Web masters to feed Google pages they would like to have indexed. Up until now, Web masters had no control over what pages Google crawled. Web masters could only submit their homepage to Google and hope that Google would crawl through links to find the rest of their Web site.Google's new service, Google Sitemaps, provides Web masters with a method to inform Google exactly which pages they want crawled, how often these pages change and the order that these pages should be crawled.Stop waiting:Whether your Web site contains a single Web page or millions of pages, Google Sitemaps are useful for any business with a Web site. If you want Google to crawl more of your Web pages or you want to be able to tell Google when your Web pages change, then you should be using Google Sitemaps.Google Sitemaps are particularly beneficial for parts of a Web site that cannot be reached by Google's crawler. For instance, dynamic...

New Tools Offer a Reality Check for Consultants? Marketing
San Francisco, CA (ContentDesk) September 14, 2005 -- "About Us." "Our Qualifications." "Our Clients." Too many consultants' Web sites are plagued with the royal "We" syndrome. This inward focus is just one of the shortcomings of many consultants' Web sites.As a result, the message of many consultants' sites falls on deaf ears. "It seems as though many of these consultants are breathing too much of their own air," says Michael W. McLaughlin, the co-author of Guerrilla Marketing for Consultants and a consulting industry veteran.McLaughlin created a free, automated assessment tool to help consultants analyze the marketing power of their Web sites.
The Guerrilla Consulting Web Site Self-Assessment is available at the following URL: http://www.automatedassessments.com/assessment.aspx?id=144.Industry jargon is another problem that plagues consultants' communications, both on the Web and offline....
Advantages of portable oxygen generators
Improvements in technology now allow the creation of portable oxygen generators, which are highly useful for people who need supplemental oxygen for breathing, and for other applications like food sterilization, aquarium installations, oxygen therapy, oxygen bars, and many more.
The portable oxygen generators can be installed anywhere, and they can simply be used to raise the oxygen level in the environment and clear the polluted air in the rooms. Processes inside the body consume high amounts of oxygen, and scientists discovered that in the ancient times the levels of oxygen in the atmosphere Were twice as high as they are now. So, having a simple to use, portable oxygen generator to raise the levels of oxygen can help you work and feel better.
Also, there are some people who are suffering from a disease called oxygen deficiency. This disease manifests by causing bronchial problems, dizziness, fatigue, depression, a low immunity to influenza, to...
