An electric generator is basically an electric motor working backwards. An electric motor converts electrical energy into mechanical energy‚ and an electric generator converts mechanical energy into electrical energy. An electric generator looks almost identical to an electric motor. Each consists of a loop that is able to rotate in a magnetic field. The electric motor uses electrical energy to make the loops rotate which creates mechanical energy. In the electric generator it uses mechanical energy

most electricity. If there are more coins in the pile‚ then the more electricity it can produce‚ because the more electrons you have‚ the more electricity you will get. Batteries are expensive‚ but you can make one for exactly 24 cents! In this experiment‚ you will make your own voltaic pile using pennies and nickels. In the data‚ we will see if the number of pennies and nickels will affect the number of voltage and current. Problem How many coins in the pile will make the most electricity? Hypothesis

Not much over a hundred years ago‚ electricity‚ except in the form of lightning‚ was an unknown force. Its discovery was due to Michael Faraday‚ the great English scientist. On one occasion‚ about 1830‚ he was showing one of his early experiments to a distinguished company at the Royal Institution in London. He showed that when a magnet was brought suddenly near a coil of wire‚ a slight current of electricity was produced in the wire. Afterwards a lady said to him‚ "But‚ Professor Faraday‚ even if

lack of planned investment in the power sector‚ load shedding has become the flagship phenomenon of the country’s electricity system. Some parts of the city of Sylhet may face black outs for more than 8 hours a day during the very hot summer. The power shortage eventually leads to the failure of water supply. Most citizens have to face a miserable life with little water and no electricity under the scorching tropical heat. There are no

CONCLUSION……………………………………. ABSTRACT Electricity or light from electricity has become a contributor to students’ ease in doing projects and assignments. Moreover‚ this electricity or electrical light helps students and professors in delivering the lessons well and effective. With the absence of this electricity‚ it is harder for students to work fast and efficient and with that also‚ the rush for deadlines and better outputs. Thus‚ electrical light or electricity is significant in the everyday life

the traditional way of learning which was to learn completely from books and instead tried investigating and experiments of his own to find out information. He became famous for his experiments with electricity and magnetism which he published books on. William Gilbert first coined the term "electricity" from the Greek word for amber. Gilbert wrote about the electrification of many substances in his "De magnete‚ magneticisique corporibus". He was also the first person to use the terms electric force

ELECTROSTATICS INFLUENCE OUR LIVES? INTRODUCTION We all are familiar with the term electricity which comes from batteries and which is used to light bulbs‚ buzzers‚ and other electrical devices. We also know that conductors are those objects which conduct electricity easily and insulators do not conduct electricity at all. This is basic knowledge but right now we are going into detail about electricity and static electricity. ELECTROSTATICS Many of us have this wrong concept in our mind that insulators

MOTORS ANDis geared to using electricity. industrialised society GENERATORS Electricity has characteristics that have made it uniquely appropriate for powering a highly technological society. There are many energy sources that can be readily converted into electricity. In Australia‚ most power plants burn a fuel‚ such as coal‚ or use the energy of falling water to generate electricity on a large scale. Electricity is also relatively easy to distribute. Electricity authorities use high-voltage
