followed by the explicit mention of the applications of electronic electroscope. A list of important components that form an integral part of this project topic has been made. 1.Introduction In most experiments dealing with static electricity‚ an electroscope is required to indicate the presence of small amounts of positive or negative charge in laboratories‚ gold leaf electroscopes being one of them. However‚ these gold leaf electroscopes may be too delicate and costly for the average

Electric Cars An electric car is a vehicle which gets power from one electric motor or more‚ and an electric car use electrical energy to store batteries or another energy storage device. The developmental history of electric cars is very long‚ and the first automobile all over the world was an electric car. However‚ electric cars had two terrible disadvantages: the problem of energy technology and mileage limit around 20 century. The problems made electric cars disappeared from citizens eyes for

that Nature is almost Physics (apart from the fact that the word Physics itself is derived from Greek "physis" meaning nature). Physics is all around us. We can find Physics as the backbone for any daily life example such as an electric light‚ electricity‚ the working of our vehicle‚ wristwatch‚ cell phone‚ CD player‚ radio‚ plasma TV set‚ computer‚ and - the list goes on Physics and its principles are integrated with almost everything you do. A few of the things physics controls are how: •

is given different names at different places but the main aim of the grid is to ensure the transfer of power from multiple input points to multiple output points at places known as stations or substations. The electricity that passes through these lines is generally high voltage electricity and hence there are multiple mechanisms by which the same can be done at different places for different purposes. The electrical wires that are visible up in the sky connected to different poles are one of the

· 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. ·

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

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

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
