The most obvious advantage of electric car batteries is that they don’t produce the pollution associated with internal combustion engines. According to the Electric Vehicle Association of Canada‚ or EVAC‚ even EVs recharged from coal-powered electric generators cut carbon emission roughly in half. EVs recharged from cleaner forms of electrical power generation‚ such as hydropower and nuclear plants‚ can reduce carbon emissions to less than one percent of those currently produced by internal combustion

5561 - A World with Only Electric Vehicles Today our lives are thought to be in danger due to global warming. Global warming is defined as a gradual increase in the overall temperature of the earth’s atmosphere caused by increased levels of carbon dioxide‚ chlorofluorocarbons‚ and other pollutants. Thought to be a big contribution to global warming are the emissions that come from the exhaust of our cars. Electric vehicles do not have tailpipes that exhaust fumes to pollute so they are the logically

inhumanity of the death penalty‚ including the barbaric methods and public spectacle of the act prior to William Kemmler‚ and most importantly‚ the safety and efficacy of direct current versus alternating current in the eventually preferred method of the electric chair. Thomas Edison and George Westinghouse‚ along with a few others‚ were the players who manipulated how the public‚ and therefore the lawmakers‚ felt about this social policy. As it is today‚ the death penalty was a big debate issue in the

Classifications of the Hybrid Electric Vehicles: The hybrid electric vehicles (HEV) are the special types of vehicles that make use of two things together‚ i.e. conventional internal combustion engine (ICE) and an electric propulsion system‚ which together help in achieving fuel efficiency as compared to any other vehicle. The degree of efficiency and improvement provided by the HEVs depend on the degree and the type of propulsion systems they make use of. The engineers have succeeded in adding

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

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

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

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

structures 1. This drill contains an electric motor. The diagram below shows the main parts of an electric motor. The carbon contacts are made of graphite. Springs push the contacts against the copper ring. The contacts conduct electricity to the copper ring. The copper ring rotates rapidly but does not stick or become worn because the graphite is soft and slippery. Graphite has properties which are ideal for making the contacts in an electric motor. Explain‚ in terms of structure and
