Electricity and Magnetism Electricity Circuit symbols Potential difference The energy which is delivered to an electric circuit comes from the supply. The greater the potential difference of the power supply the more energy is delivered. Potential difference is measured in volts‚ which has the unit symbol V. Cells in series The more chemical cells that are connected in series the greater the potential difference that they supply. The potential difference of a number of cells connected

Electricity and Magnetism History Electromagnetism Originally electricity and magnetism were thought of as two separate forces. This view changed‚ however‚ with the publication of James Clerk Maxwell’s 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions‚ all of which have been clearly demonstrated by experiments: 1. Electric charges attract

Electricity generation is the process of creating electricity from other forms of energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire‚ or disc of copper between the poles of a magnet.[1] For electric utilities‚ it is the first process in the delivery of electricity to consumers. The other processes‚ electricity

Electricity’s impact on Society Electricity has had multiple impacts on society both positve and negative. Electricity has had an effect on everyone in the world‚ even though some people have no understanding or have no use for electricity. For example‚ there are tribes in the Amazon who have never seen a lightbulb who have never beared witness too the heracy of Big brother and yet they are still effected by electricity. The chainsaws which cut down their beloved forests are designed by a man called

1. Life before the internet versus after the internet. Waking up on a Saturday morning to beat the morning rush and run some arens; ordering mail in catalogs to view the most current products available; needing to wait for news bulletins to see what’s going on in the world; having to go to the library and use xeroxes for homework; these where all part of the day to day lives we used to have prior to the internet.

Electrostatic Field • An electrostatic field is a phenomenon that is very similar to a magnetic field. When an object is electrically charged‚ it creates an electrostatic field. If an object has an excess of electrons‚ then it’s considered to have a negative charge. If an object has fewer electrons than its surrounding environment‚ though‚ it’s considered to be positively charged. Just like with magnetic fields‚ two objects that are oppositely charged will attract each other. This scientific

Early History of Electric Power Date Event Pictures 1800-1819 Early electric experiments were performed with DC. In 1800‚ Alessandro Volta published a description of a silver/zinc battery‚ acknowledging that he did not know how it worked. In 1807‚ Humphry Davy constructed a practical battery (the picture will be immediately familiar to anyone who works with UPS systems)‚ and demonstrated both incandescent and arc light. • Volta’s famous bi-metalic frog twitch (I did this one myself as a boy..
