WHO INVENTED ELECTRICITY?
It will not be wrong to describe
electricity as being widely-used.
The application of electricity has
grown to the point where most of us lead
“electrified lives” surrounded by a
variety of devices that use electric
energy.
Who invented electricity? A chain
of inventions of electricity led to the modern-day use of electric power. Lightning is
the purest and most basic form of electricity. It required great effort to bring this
energy in everyday use. Here we give you some of the most famous names in the
history of the discovery of electricity.
Benjamin Franklin discovered electricity through his well-known experiment
of flying a kite during a thunderstorm. On June 15, 1752 Benjamin Franklin tried to
prove his theory that lightning was electrical, through his experiment of flying a kite
during a thunderstorm.
Michael Faraday discovered that moving a magnet inside a wire coil could
make electricity. He was able to build the first electric motor. He later built a
generator and a transformer. This has become his great contribution to the field of
electromagnetism.

Volta discovered that chemical reactions could be used to create cathodes and
anodes. The difference of electric potentials between them could lead to the flow of a
current between them.
Thomas Edison’s invention of the electric light bulb (lamp) was a unique
invention. It led to the creation of an electric power system.
So, we see that the history of electricity runs from the period before Christ up
to the computer age today.
