Nikola Tesla was a Serbian-American engineer and physicist who made many breakthroughs related to electricity in the late 19th century. He invented the alternating current motor and developed AC power transmission technology. Some of his other inventions included the Tesla coil, which can produce high-frequency alternating currents, and an early wireless transmission system. Tesla received over 700 patents for his inventions and worked with George Westinghouse to commercialize alternating current electricity. While some of his ideas were ahead of their time, Tesla made many contributions to the development of electrical power systems still used today.

3. 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.

4. Chances are that you have already seen this
invention. It is a transformer used to produce high-
voltage, low-current, high-frequency alternating-
current electricity. To observers, it appears as if
lightning is being shot into the air.
A Tesla coil consists of a primary coil and
secondary coil, each with its own capacitor to
store electrical energy. The two coils and
capacitors are connected by a spark gap. A high-
voltage source powers the system.

5. By running a wire connected to the resonator around his
lab he permeated his lab with electromagnetic energy
and was able to light a fluorescent bulb held in his hand
because the voltage drop through the air was great
enough to cause a sufficient current flow.
Using a magnifying transmitter, he was also
reportedly able to light a field of bulbs at a
distance of 1 km. The magnifying transmitter was
an adaptation of the Tesla coil,
•

6. Tesla saw the rise of the piston engine in the
automobile industry as a way to make a change
in the world. He developed his own turbine-style
engine that used combustion to make disks rotate.
The fuel efficiency of his engine was as high as 90%, a
big achievement considering this is similar to the
efficiency of some modern turbines.
•

7. Before his lab burned down, Tesla discovered that
he could use his coils to transmit and receive
powerful radio signals, tuning them to resonate at
the same frequency. By early 1895, he was ready
to transmit a signal 50 miles from his lab, to West
Point, New York. But the fire in Tesla's lab destroyed
his work.
While he was rebuilding, a young Italian experimenter
named Guglielmo Marconi, who was working in
England, took out the first wireless telegraphy patent.
•

8. The first AC commutator-free three-phase
induction motor was invented independently by
Galileo Ferraris and Nikola Tesla. Although Ferraris
presented his engine first, in 1885, it was Tesla who
filed for a patent first.
George Westinghouse, who was developing an
alternating current power system at that time, licensed
Tesla's patents in 1888. This type of motor is commonly
used in vacuums, blow dryers, and power tools, even
today.
