Direct Current. His opponent, Nikolas Testa, wanted Alternating Current.
Very strongly. Edison went so far as to make a movie of an elephant being executed with AC.
by rectification
The introduction of alternating electrical current, in 1920, eliminated the need for a return wire. Alternating current, AC, replaced direct current, DC.
An inverter or a motor-generator set.
the two types of electrical current are AC which stands for Alternating current and DC which stands for direct current. Battery current is direct current. The electrons in alternating current flow one way and then flow in the opposite direction.
In the "War of Currents", George Westinghouse and Thomas Edison became adversaries due to Edison's promotion of direct current for electric power distribution over alternating current advocated by Westinghouse and Nikola Tesla. AC was and it is the best system.
Very strongly. Edison went so far as to make a movie of an elephant being executed with AC.
Thomas Edison used direct current in his electric power transmission in the 1800's.This isn't very relevant, but it is "Quite Interesting"From QI--Elephant in the Room: In 1903, Thomas Edison made a film called Electrocuting an Elephant, in which he used an alternating current to kill an elephant called Topsy. He used the film as a propaganda film to destroy the reputation of alternating current, owned by Westinghouse, believing his direct current was safer. He tried to encourage people to call being electrocuted, "Westinghoused".
Thomas Edison believed it was dangerous to fool around with alternating currents and promoted the use of direct current instead. He was in a bitter rivalry with Nikola Tesla, who championed the use of alternating current for its efficiency over long distances.
Thomas Edison favored and promoted DC current. He claimed it was safer than AC. However it was almost impossible to send DC current over a long distance so AC became the standard for the world.
Thomas Edison tended to hold on to a particular idea too long. As a result Edison held on to the idea of using direct current instead of alternating current much too long. Edison invented the diode. When the triode was invented Edison continued to try to accomplish with the diode what the triode accomplished easily. His weakness was he did not see when an idea should be dropped.
direct current .
Alternating current. Direct current is used in batteries.
Nikola Tesla first patented alternating current, but it became popular when Westinghouse, a company that provided electrical power by AC, became the official power company for the 1893 World's Fair in Chicago.
Alternating current is better than direct current for transmission.
An ac motor basically makes it easier electricity form.A man Named Nikola Tesla created Alternating Current. (AC) AC is the flow of electricity going back and fourth, unlike Direct Current. (DC) A man named Thomas Edison created Direct Current.
Power lines carry electricity as alternating current.
