off machines when you leave a room (examples include TV’s‚ computers‚ radios‚ stereos‚ video games‚ VCR’s‚ and DVD players). * When you go away on a trip‚ be sure to unplug these same machines because they have stand-by functions that consume electricity even when they are turned off. * Fill your dishwasher efficiently and limit the number of times you run it. * Don’t put furniture and other things in front of heating and air conditioning vents. * Keep doors and windows closed when heat

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

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

CHAPTER - 12 ELECTRICITY HOTS Questions for Practice 1. Name a substance whose resistance almost remains unchanged by increase of temperature. 2. Name two special characteristics of heater coil. 3. A wire of resistance 4 ohms is bent to form a circle. What is the resistance between two diametrically opposite ends? 4. How does the resistance of a conductor change if its temperature is increased? 5. A current of 4A flows in a wire of resistance 60 ohms. Calculate electrical energy consumed in 2 minutes

David M Professor H English 24 November 2013 Visual art is important because it allows one the freedom of personal expression‚it’s a fun activity‚ and its nonverbal way of getting the point across. People seem to gravitate towards images ‚giving them a meaning from their own personal lives. That they themselve are able to relate back to their : concept of what life is‚ memories of their yester-year and their dreams to be. Understanding what’s going on when a face begins to squish ‚to make

Importance of Computer in human society As we hurtle towards the 21st century‚ we must accept the inevitability of a computer revolution in the near future. It is an-inseparable part of development‚ as demonstrated by other countries. Computers are no longer luxury or the sole property of the advanced countries. Their appropriate uses in India can help us solve the unique problems of a developing country and bring about the desired changes in increasing literacy‚ optimizing resources‚ increasing

Electricity is important in our everyday lives. It is essential for almost everything in our modern world. The knowledge learned in the past about electricity enabled such things as engines‚ telephones‚ radios‚ computers‚ and much‚ much more. As early as 600 B.C.‚ the Greeks were already studying electricity. They noticed that if you rubbed a piece of amber with fur‚ it had a charge with the ability to attract small objects. Many years later‚ in the 16th Century‚ William Gilbert discovered many

The importance of the army in Spartan society: The entire Spartan society revolved around the army‚ essentially making it the key aspect of Spartan life and culture. The army influenced areas such as education and social structure as well as being the most important defence of Sparta in both combat and reputation. After an embarrassing defeat at the battle of Hysiai Sparta went through great military change‚ these changes dramatically changed all other areas of Spartan life‚ turning Sparta into

Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is
