In 1700 Ben Franklin found that the origin of lightening and
electricity was the same and this finding made the things easier
for people in the future.
Michael Faraday (1830-1839) made a device, which was based on
electromagnetism, generation and transmission.
In 1860 these years the theory of electromagnetic from
mathematical point of view was introduced. Maxwell opened a new
chapter in the field of physics by unifying magnetism; light and
electricity. The most important development of the century was
introduction of Maxwell’s four laws of electrodynamics, and then
called Equations of Maxwell. This was the main source for
development of electricity, TV and other electric devices.
