Project report submitted on: Transformers Class: 12 Submitted to: Mr. Jonny beaver‚ Physics teacher Submitted by: Mohammed Al Khabori 19 February 2011 Theoretical report Transformers I have generated series of questions‚ regarding the transformers‚ which are to be researched and answered. They are the following: * What is the history of transformers? * What is a transformer? * Which principle/laws does the transformer obey? * How can we construct a transformer?

electro-chemical devices. CONTRIBUTION to SOCIETY Alessandro Volta‚ Italian physicist‚ known for his pioneering work in electricity. Volta was born in Como and educated in the public schools there. By 1800 he had developed the so-called voltaic pile‚ a forerunner of the electric battery‚ which produced a steady stream of electricity. In honor of his work in the field of electricity‚ the electrical unit known as the volt was named in his honor. Marie Curie AUTOBIOGRAPHY Inventor: Marie Curie

To do and not to do with electricity Hey! Are you among those who enjoy doing their work on their own? If yes‚ then this one’s for you!! I understand how good it feels to have your work done on your own‚ save money and somehow‚ getting into the expert’s shoes. One thing most of these people forget is that it can just be lethal down the line doing things one doesn’t know about. Especially‚ when it comes to doing an electrician’s job! That’s when a professional electrician comes into the picture

Domestic Technology in the past There is information about the history of domestic technology and its effect on gender involvement in the home (ca 1850 - 1990). These are mainly changing standards‚ the nature of family life‚ and new roles for women in the home. Instead of removing housework‚ domestic technology accompanied to a re-definition of how this work must be organized and done. Housework in the 19th century The 19th century home The organization‚ physical effort

alternative source of energy is the fact wind speed must be at least greater than 10 miles per hour‚ and this is not a constant situation (Green living‚ 20130). However‚ when wind speed is greater than 12 miles per hour‚ can generate 70 % more electricity‚ and the best approach to ensure such scenario is building platforms for the fans at higher altitudes (Green living‚ 2013). In case wind increases too much‚ it can damage the wind turbines‚ therefore most of the wind turbines automatically shut

· Thermostat : When we switch on the electric iron current flows throught the heating coil. The heat in the heating coil causes expansion in the thermostat which gradually disconnects the supply. · Heating Coil : a coil made of metal so when electricity flows through it‚ it gets hot and it transferes this heat to the sole plate. · Sole plate : it’s a a flat triangular surface cast of aluminium coated with a non-stick PTFE or stainless steel. It’s heated and press clothes to remove creases. ·

centimeter based on a calculation for a single Nano wire.. Advantages of the Nano generators are small size‚ efficient‚ large scale production and portable. By converting mechanical energy from body movement‚ muscle stretching or water flow into electricity‚ these "Nano generators" can make it possible to emerge into a new class of self-powered implantable medical devices‚ sensors and portable electronics. There is no

that it is a resistant material that will slow electric current down‚ therefor‚ it will produce heat and some light. I think that the more nichrome wire that we use the ampere will be lower‚ I think that is because the longer the wire is‚ the more electricity that the wire will slow down. Apparatus - Power Supply - Wires (Leads) - Alligator Clips - Ammeter - Nichrome Wire (20 Gauge)-(different length) (2 cm‚ 4 cm‚ 6 cm‚ 8 cm‚ 10 cm) Method 1. Set up the power supply. 2.

When Gustav Robert Kirchhoff’s banker questioned the financial unreliability that would result from Mr. Kirchhoff investing his hard-earned gold in Fraunhofer lines‚ Kirchhoff handed him the medal he had earned from his research and replied “Look here‚ I have succeeded at last in fetching some gold from the sun.” Despite how phenomenally sassy this quote makes him appear‚ Kirchhoff lived a quiet life (aside from his incredible scientific contributions‚ of course). Gustav Robert Kirchhoff was born

A superconductor is a metallic alloy that conducts electricity without resistance‚ below a certain temperature. Once in motion‚ an electrical current will flow in a closed loop within a superconducting material. This is the closest to scientists of a perpetual motion machine. In 1911‚ Heike Kamerlingh Onnes first observed superconductivity. He used mercury and cooled to four degrees Kelvin. When the mercury reached that temperature‚ the resistance disappeared. That meant that the electrical current
