Lesson 11. Topic “Heating effect of an electric current”. Grammar material: Articles. Text: “Heating effect of an electric current”. The production of heat is perhaps the most familiar among the principal effects of an electric current‚ either because of its development in the filaments of the electric lamps or‚ may be‚ because of the possible danger from overloaded wires. As you know‚ of course‚ a metal wire carrying a current will almost always be at a higher temperature than the temperature of

Einstein). Electric cars are automobiles they use one or more electric motors‚ other than using more common gasoline powered engines. Electric cars use batteries; batteries are used to store energy. Since Electric motors don’t have to warm up they have instant torque‚ creating strong and smooth acceleration‚ which can give you a more satisfying ride. Electric cars are safer and better than gasoline powered cars‚ since they aren’t polluting the air as much as gas powered cars. Electric cars are high

Ms. Haynes 2nd Period May 21‚ 2012 Electric Cars There is a big debate about the future of the auto industry. The new big topic is electric cars. Ads emphasize how much less pollution these cars put out‚ but the truth is that many people do not realize the downside of these cars. For instance‚ did you know that average battery cost for electric cars is between $18‚000 and $20‚000? Also‚ these cars produce significant more amounts of sulfur dioxide compared to traditional internal combustion

Who Killed the Electric Car? is presented as a whodone- it mystery. Staying true to this genre‚ the film opens with necessary background information‚ describes the crime committed‚ answering all of the what‚ where‚ and when questions‚ and then in the style of Sir Arthur Conan Doyle gathers the suspects for close scrutiny‚ coming to a conclusion on the guilt or innocence of each. Opening with a bit of automotive history that establishes the electric car as a competitive alternative to the

Keys to High Performance In the assigned case study we see the history of Lincoln Electric and the success it has had with innovative leadership techniques found in companywide quality management‚ or Theory Z (Houser‚ 1995). Through the use of well executed human resource management practices (Schuler & MacMillan‚ 1984)‚ Lincoln Electric has created a competitive advantage through the use of its people (Summers‚ 1994)‚ which accounts for its high performance over the years. The way a company organizes

introduced the EV-1 electric car in California and Arizona. Hundreds of the electric cars were soon on the road. Then they all disappeared. The mystery behind their disappearance is the subject of the documentary "Who Killed the Electric Car?" Electric vehicles had many advantages over their competitors in the early 1900s. They did not have the vibration‚ smell‚ and noise associated with gasoline cars. Changing gears on gasoline cars was the most difficult part of driving‚ while electric vehicles did not

Magnetic effect of electric current is one of the major effects of electric current in use‚ without the applications of which we cannot have motors in the existing world. A current carrying conductor creates a magnetic field around it‚ which can be comprehended by using magnetic lines of force or magnetic field lines. The nature of the magnetic field lines around a straight current carrying conductor is concentric circles with centre at the axis of the conductor. The direction of the magnetic field

Who Killed the Electric Car? Video Discussion Questions Summary: It begins with a solemn funeral�for a car. By the end of Chris Paine’s lively and informative documentary‚ the idea doesn’t seem quite so strange. As narrator Martin Sheen notes‚ "They were quiet and fast‚ produced no exhaust and ran without gasoline." Paine proceeds to show how this unique vehicle came into being and why General Motors ended up reclaiming its once-prized creation less than a decade later. He begins 100 years ago

THE RELATIONSHIP OF ELECTRIC FIELD INTENSITY AND ITS DISTANCE FROM THE CHARGED OPOINT PHYS-232 JIANSONG HE GROUP: Abstract This experiment was performed to find the electric field strength from different distance to the charged point. The field strength was determined statically‚ by measuring its electrical potential when subjected to loading‚ and dynamically‚ by measuring the electrical potential at different location on the conductive paper. The electrical potential was measured from three
