HISTORY OF ELECTRICITY Depite what you have learned‚ Benjamin Franklin did not "invent" electricity. In fact‚ electricity did not begin when Benjamin Franklin at when he flew his kite during a thunderstorm or when light bulbs were installed in houses all around the world. The truth is that electricity has always been around because it naturally exists in the world. Lightning‚ for instance‚ is simply a flow of electrons between the ground and the clouds. When you touch something and get a shock

things of the past. We now light our lamps with electricity. Switch on the button and there is the day-like light even in the darkest night. In summer seasons electric fans‚ air conditioning plants are used to provide us with cool atmosphere. In winter‚ heating plants are used to keep the room warm. Electric bells‚ press and stove are things of every-day use. People keep refrigerators in their homes to keep their food in a fresh condition. Indeed electricity serves as a faithful domestic servant in daily

Lecture Notes: Basic Electricity Fall 2011 This course module introduces the basic physical models by which we explain the flow of electricity. The Bohr model of an atom – a nucleus surrounded by shells of electrons traveling in discrete orbits – is presented. Electrical current is described as a flow of electrons. Ohm’s law – the relationship between voltage‚ current and electrical resistance – is introduced. Learning Objectives Understanding the basic principles of electricity is a foundational

What is WiTricity ? -WiTricity‚ stands for wireless electricity‚ is a term coined initially by Dave Gerding in 2005 and used by a MIT research team led by prof. Marin Soljačić in 2007‚ to describe the ability to provide electricity to remote objects without wires (wireless power transfer). This could be useful to power consumer and industrial electronics like cell phones‚ laptops‚ etc. -WiTricity‚ a portmanteau for "wireless electricity"‚ is a trademark of WiTricity corporation referring to their

SECURITY OF WIRELESS COMMUNICATIONS Introduction Wireless devices‚ like all technologies that provide external access to corporate networks‚ present security challenges. With wireless standards and practices still rapidly evolving‚ it is important to understand the strengths and limitations of available technologies in order to implement a secure solution. Extending current security policies to encompass wireless devices requires an understanding of the security features of both wireless devices and

Introduction Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or the entire communication path. The first wireless transmitters went on the air in the early 20th century using radiotelegraphy (Morse code). Later‚ as modulation made it possible to transmit voices and music via wireless‚ the medium came to be called "radio." With the advent of television‚ fax‚ data communication‚ and the effective use of
