Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects, such as lightning, static electricity, electromagnetic induction and the flow of electrical current. In addition, electricity permits the creation and reception of electromagnetic radiation.
Nigel's yoga is just one of the features of this exclusive yoga retreat located along a lake in lush northern Sri Lanka, an hour from the ancient city of Anuradhapura. The brain child of South African Giles Scott and Sri Lankan Viren Perera, who bought the property 15 years ago as "a nice piece of land" and a chance to "hang out and live in village culture" (they planted thousands of trees, from kumbuk to ebony, and landscaped its rushing brooks and weirs), today Ulpotha offers trips to temples, copious organic vegetarian meals, herbal teas served from boiling pots over a fire, a tree-house on the lake to sleep in if one wishes and a full platter of ayuredic treatments, including an oil drip on the forehead. What I most like about this retreat: the absolute cut-off from my urban lifestyle. To begin with, no electricity, but kerosene lanterns that line the maze of swept red-earth paths through the forest. To charge my computer, the staff brings it daily to the nearby village to plug it in, and returns it to me at night. All I hear are frogs, birds and the rushing sound of the brook that runs at the edge of my hut. It is like sleeping next to a waterfall, but in the most comfortable bed in the world (the mattresses are hand-made by Sri Lankans), removed from Internet, cell phones, contact lenses and all customary habits.
On this electricity-free yoga retreat, people got to experience life without electricity for a while. They say it is nice to be cut off from the rest of civilization having no phones, computers, or any of that. Electricity is definitely a magnificent aspect of human lifestlyes, but maybe a little time without it might be beneficial to some.
Richie's Ruhmkorff coil is an instrument consist[ing] of a primary coil of copper wire, with its core or bundle of iron wire; over this is a thick glass cylinder or bell; surrounding this bell is the secondary helix of fine silk-covered copper wire of various lengths wound upon a cylinder of gulfa percha and carefully insulated. The power of this machine is immensely greater than the Electrical machine; the discharges being so rapid that they produce the effect of a continuous flow; and with quantity so great that a leyden jar can be charged and discharged so rapidly that it is difficult for the ear to distinguish the sounds and with almost deafening effect.
This educational lecture was held in 1866. It talks about different machines that produced rapid firings of electricity. It is quite incredible how far technology in electricity has come from then. Instead of bulky machines that produce electricity we have outlets in almost every home that we can put cords in to allow the flow of electricity.
Units of electrical measure which have been used in scientific investigations for more than a decade have come into use in the practical application of electricity and have been accepted as necessary and sufficient in all countries. A formal international agreement upon the names and precise definitions of these units was necessary before it was desirable to fix them by legislative enactment. This agreement has now been reached after several preliminary conferences, and is to be found in the official report of the chamber of delegates on the International Congress of Electricians.
Because suppliers of electricity and natural gas provide a service before billing for it, they essentially extend credit to their customers. As creditors, these suppliers are subject to several laws designed to protect consumers from unfair or discriminatory lending practices. For example, if your company provides services on credit, you may be required to meet certain billing standards under the Fair Credit Billing Act. If your company provides information about customer accounts and delinquencies to a credit reporting agency, you must take certain steps to ensure the information is accurate and private. In addition, the Equal Credit Opportunity Act prohibits companies from discriminating in granting credit on the basis of sex, marital status, age, race, national origin or receipt of public income assistance.
When you tie a free offer to the purchase of another product or service, its deceptive to increase the regular price of the purchased product to cover the cost of the free item. It would be deceptive to lure consumers with an offer of free electricity for the first month of a contract if the cost of the electricity would be factored into the following months bills.
Electricity is the flow of electrical power or charge. It is both a basic part of nature and one of our most widely used forms of energy. Electricity is actually a secondary energy source, also referred to as an energy carrier. That means that we get electricity from the conversion of other sources of energy, such as coal, nuclear, or solar energy. These are called primary sources. The energy sources we use to make electricity can be renewable or non-renewable, but electricity itself is neither renewable or nonrenewable.
Electricity powers our world and our bodies. Harnessing its energy is both the domain of imagined sorcery and humdrum, everyday life -- from Emperor Palpatine toasting Luke Skywalker, to the simple act of ejecting the "Star Wars" disc from your PC. Despite our familiarity with its effects, many people fail to understand exactly what electricity is -- a ubiquitous form of energy resulting from the motion of charged particles, like electrons. When put to the question, even acclaimed inventor Thomas Edison merely defined it as "a mode of motion" and "a system of vibrations."
Thomas Edison didn't invent the first light bulb but he did invent one that stayed lit for more than a few seconds. Thomas Edison invented more than 2,000 new products, including almost everything needed for us to use electricity in our homes: switches, fuses, sockets and meters. Ben Franklin didn't discover electricity but he did prove that lightning is a form of electrical energy.
A flow of electric charge constitutes an electric current. In order for a current to exist in a conductor, there must be an electromotive force (emf) or potential difference between the conductor's ends. An electric cell, a photo-voltaic cell, and a generator are all sources of emf. An emf source with an external conductor connected from one of the source's two terminals to the other constitutes an electric circuit
All matter is made up of atoms, and atoms are made up of smaller particles. The three main particles making up an atom are the proton, the neutron and the electron. Electrons spin around the center, or nucleus, of atoms, in the same way the moon spins around the earth. The nucleus is made up of neutrons and protons. Electrons contain a negative charge, protons a positive charge. Neutrons are neutral – they have neither a positive nor a negative charge.
