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

This study aims to make an improvised traveling charger that will use heat or waste heat to charge a battery. It is not new to us that we are lacking for the supply of the electricity and being in the modern times‚ we can’t live without cell phones and how does we able to charge the battery if there’s no supply of electricity. The researcher used scrap materials that can be easily found. They used copper and iron plate‚ some adhesives copper wires and the normal traveling charger to construct the

Importance of electrical services in buildings Electricity has been part of our lives. It has brought many things that surely have made many wonders and life would seem so hard without it. Electricity powers our light‚ heating‚ electronic appliances such as computers and television‚ and a host of essential services that we take for granted. However‚ electricity has much more important aspects because it is a fundamental feature of all matter. Electricity is the force that holds together the molecules

Electricity is a complex branch of physics that plays an immensely important role in our lives. In both the articles Energy Story by the California Energy Commission and Conducting Solutions by Rodney Schreiner we are given a fairly in-depth explanation to this fascinating tool. In a 2011 TED talk a speaker named AnnMarie Thomas introduces us to an intriguing concept‚ using playdough to conduct electrical experiments. All of these sources purposes are to help us better understand electricity.

Case Study: What’s the buzz on Smart Grids 1) How do smart grids differ from the current electricity infrastructure in the United States? The main difference where the smart grids differ from the current electricity infrastructure in the United Sates is that there is no information currently available as to how much energy/electricity is being used and where it is being used. In simple words it can be said that currently there is no exchange of information between the provider and the consumer
