The untold story of Nikola Tesla. Know something unknown.

2. Who is Nikola Tesla?
• Nikola Tesla was born on 10 July 1856
into a Serb family in the village of
Croatia.
• Nikola Tesla was a Serbian American
inventor, electrical engineer, mechanical
engineer, physicist, and futurist best
known for his contributions to the design
of the modern alternating current (AC)
electricity supply system.

3. n’s help
• On june 6th 1884 he went to United
States .
• And was hired by Thomas Alva Edison
to do basic electrical engineering to
redesign the direct current generator
in Edison’s business.

4. Alternating current
• Tesla then left Edison and went to
George Washington to commercialize
his system of alternating current in
1888 .
• But the problem here was AC was
competing DC which was developed
by Edison.

5. Current war

6. • Edison started spreading false information on
AC .
• “Hundred of people are suffering from
alternative current symptoms it is very bad”

7. • Thomas Edison electrocute elephant rather
killed them by showing how dangerous
electric current was .

8. Alternating current
• Alternating current was however demanding as :
• DC could pass current only 2 miles maximum that
means for every 2.5 km there should be electric
substation, whereas in AC it was about 100 of
miles.
• AC was fast and reliable and cheap compared to
DC.
• Light running on AC was bright light unlike dim
yellow light of Edison's DC

9. Truth behind light bulb:
• We might heard that Edison was the man
behind light bulb but sorry to say it was not
right,22 people were simultaneously working
on light bulb but Edison had best marketing
skills .
• Nikola Tesla invented and perfected 24
different machines which would replace
Edison's models.

10. Tesla’s projects:
• Tesla was the 1st man to invent hydroelectricity
when AC was accepted , it was used in a power
station at Niagara falls. This was when first
hydro power was invented .
• In 1901 Wilhelm Rontgen was awarded the
noble prize in physics for discovering the X-Ray
but the truth is that Tesla had already invented
it refused to experiment it.

11. Tesla ‘s project :
• In 1909,the noble prize in phiycs was awarded
jointly to Marconi and Karl Ferdinand for
inventing radio. All they did was duplicated
Tesla’s project .
• When Tesla came to know about it he said
“Marconi is a good fellow let him continue he
is actually using my 17 patents” .

12. Tesla’s project:
In 1935 Robert Watson had recognition on
radar but again the truth was that the radar
was already invented by Nikola Tesla. Nikola
Tesla had pitched the same technology to the
U.S navy in 1917 during the advent of world
war 1. At that time Edison was the research
and development head of the US navy .
He ridiculed Tesla’s idea by saying that it had
no practical application on war.

13. Tesla’s invention:
• Tube lights
• Radio
• Radar
• Alternating current
• X-Ray

14. Tesla as hero
• Nikola tesla becam the time person
of the year when he turned 75 . He
got many medal. Honour and
apresation from albert einstein.
• The world lost tesla at the age of 86
on 7th jan 1943. But his legacy leaves
in our mind and heart .
