The importance of the alternating current ac of tesla and direct current dc of edison

The direct-current system generated and distributed electrical power at the same voltage as used by the customer's lamps and motors. This required the use of large, costly distribution wires and forced generating plants to be near the loads. With the development of a practical transformer, alternating-current power could be sent long distances over relatively small wires at a convenient high voltage, then reduced in voltage to be used by a customer. Alternating current generating stations could be larger, cheaper to operate, and the distribution wires were less expensive.

These comprised a complete system of generators, transformers, transmission lines, motors and lighting.

So original were the ideas that they were issued without a successful challenge, and would turn out to be the most valuable patents since the telephone.

An adventurous Pittsburgh industrialist named George Westinghouse, inventor of railroad air brakes, heard about Tesla's invention and thought it could be the missing link in long-distance power transmission. With more inventions in mind, Tesla quickly spent half of his newfound wealth on a new laboratory.

With the breakthrough provided by Tesla's patents, a full-scale industrial war erupted. At stake, in effect, was the future of industrial development in the United States, and whether Westinghouse's alternating current or Edison's direct current would be the chosen technology.

It was at this time that Edison launched a propaganda war against alternating current. I remember Tom [Edison] telling them that direct current was like a river flowing peacefully to the sea, while alternating current was like a torrent rushing violently over a precipice.

Why they even had a professor named Harold Brown who went around talking to audiences Meanwhile, a murderer was about to be executed in the first electric chair at New York's Auburn State Prison.

Professor Brown had succeeded in illegally purchasing a used Westinghouse generator in order to demonstrate once and for all the extreme danger of alternating current. The guinea pig was William Kemmler, a convicted ax-murderer, who died horribly on August 6,in "an awful spectacle, far worse than hanging.


The Westinghouse Corporation won the bid for illuminating The Chicago World's Fair, the first all-electric fair in history.

Up against the newly formed General Electric Company the company that had taken over the Edison CompanyWestinghouse undercut GE's million-dollar bid by half.

Electric power transmission

Much of GE's proposed expenses were tied to the amount copper wire necessary to utilize DC power. Westinghouse's winning bid proposed a more efficient, cost-effective AC system.

The Columbian Exposition opened on May 1, That evening, President Grover Cleveland pushed a button and a hundred thousand incandescent lamps illuminated the fairground's neoclassical buildings. In the Great Hall of Electricity, the Tesla polyphase system of alternating current power generation and transmission was proudly displayed.

For the twenty-seven million people who attended the fair, it was dramatically clear that the power of the future was AC. From that point forward more than 80 percent of all the electrical devices ordered in the United States were for alternating current.Electricity flows in two ways: either in an alternating current (AC) or in a direct current (DC).

Electricity or "current" is nothing but the movement of electrons through a conductor, like a wire. The difference between AC and DC lies in the direction in which the electrons flow. In DC, the. What's the difference between Alternating Current and Direct Current?

Electricity flows in two ways: either in an alternating current (AC) or in a direct current (DC). Video Comparing Alternating and Direct Current. Edison vs Tesla; Current vs Voltage; Converter vs Inverter; Electric Field vs Magnetic Field;. Edison's Revenge: Will Direct Current Make a Comeback in the U.S.?

The rise of direct current using devices and direct current generation have some rethinking the use of alternating current in the.

Brilliant scientist, terrible businessman

Oct 29,  · During the war of the currents, alternating current (AC) -- favored by Tesla -- battled for wide acceptance with direct current (DC), favored by Edison. At stake was the basis for the entire nation’s electrical system.

In the War of Currents era (sometimes, War of the Currents or Battle of Currents) in the late s, George Westinghouse and Thomas Edison became adversaries due to Edison's promotion of direct current (DC) for electric power distribution against alternating current (AC) advocated by several European companies and Westinghouse Electric based in Pittsburgh, Pennsylvania, which had .

Nikola Tesla was the inventor of the alternating current light and power system in use all over the world today.

When Nikola Tesla walked into Edison's office in , Edison was completely committed to direct current. Edison's DC system was huge and only good for very short distances.
