Detailed explanation-2: -Nikola Tesla and Thomas Edison are two of the greatest inventors in history. They each battled to dominate with their electricity transmission systems. This is the story of the war between alternating current and direct current.

Detailed explanation-3: -Soon after leaving the Edison company, Tesla was working on patenting an arc lighting system, possibly the same one he had developed at Edison. In March 1885, he met with patent attorney Lemuel W. Serrell, the same attorney used by Edison, to obtain help with submitting the patents.

His nemesis and former boss Thomas Alva Edison was the iconic American inventor of the light bulb, the phonograph, and the moving picture.

Detailed explanation-5: -Serbian-American engineer and physicist Nikola Tesla (1856-1943) made dozens of breakthroughs in the production, transmission and application of electric power. He invented the first alternating current (AC) motor and developed AC generation and transmission technology.
