who haven’t put much effort into chancing their business greener and cleaner. Firstly‚ one major threat to Estonian environment is oil shale mines and power plant in Ida-Virumaa. It has been the main source of electricity in Estonia for a long time‚ maybe even too long. Making electricity from oil shale is not only expensive‚ it is also very polluting and mining is ruining soil and ground water. Nowadays there are much more efficient alternatives to producing electric energy. The company who owns

The project “ADVANCED ENERGY METER” prepared by us can be used to find out how much electricity appliances in our house are using and how much they cost to run. INTRODUCTION If we want to save power and reduce costs‚ we need to know how much power each appliance uses over a period of time. Most appliances don’t run all the time‚ so we need

community including the isolation of aluminum‚ he is best known for his discovery that linked electricity and magnetism. While lecturing his class at the University of Copenhagen in 1819‚ he accidentally came upon this connection. Some people say that this discovery was more of an accident‚ than one based upon research and knowledge‚ which may have some truth. In the 1780’s Colomb hypothesized that electricity and magnetism were two very different laws‚ he felt this was impossible. Oersted also studied

one of Thomas Edison’s main rivals in the early implementation of the American electricity system. This man founded 60 companies‚ eventually receiving over 100 patents for his work with the desire to turn ideas into enterprises.

Electromagnetism is the study of the physical interaction that happens among electrically charged particles. This electromagnetic force is typically apparent in magnetic fields‚ electric fields and sources of light. This electromagnetic force that occurs between particles is one of the four ultimate interfaces in nature. On April 8‚ 1911 in Leiden‚ Heike Kamerlingh Onnes discovered Superconductivity. Superconductivity is the phenomenon when a material cooled below a certain temperature emits no electromagnetic
