“Persons who contributed in the
field of ELECTRICITY”
Electricity has existed as
lightning in the skies since the
beginning of the universe, even
before there was life on earth.
Early cave people probably
recognized the force of electricity
when lightning struck. They might
also have noticed the way amber
attracts light objects, or the way
certain fishes, such as the electric
eel, stun their prey. Importantly we
should know that there are some
physicist or scientist that
contributes much in the science of
electricity and they are the
A German physicist, engineer, and natural
philosopher who was most known for his
studies of air pressure.
He invented the first air pump and used it to
study vacuum and the role of air in combustion
Built the first machine in 1650 that produced
charges by rubbing ball.
Otto von Guericke's generator was described as
large sulfur ball mounted on a pole inside a
glass globe. His devise was used for early
experiments with electricity.
(December 1666 – 7 February 1736) was an
English dyer and amateur astronomer who
was the first to systematically experiment
with electric conduction, rather than simple
generation of static charges and
investigations of the static phenomena.
In 1729 he showed through experiments that
materials can affect the transfer of charges
from one object to another in analogous way
materials affect the transfer of heat from
one object to another
Gray classified materials as conductors
and non- conductors
Charles François de Cisternay Du Fay (16981739), French chemist who discovered that
electrical charges have both positive and
negative values. From the mid-18th through
the early 19th centuries, scientists believed
that electricity was composed of a fluid.
In 1733 he discovered the two types of
interactions can occur between two changes
they can attract or repel.
He conclude that there are two kinds of
charges which he name vitreous and
An American Statesman and Philosopher. In
1747, he advanced his theory of electricity
and published experiments and observation
of electricity. He used the same (+) positive
and (-) negative to identify the types of
Franklin also showed with his dangerous
kite experiments during thunderstorm that
lightning is an example of electricity.
Franklin theory was that current is due to
flow of positive charges.
Pieter van Musschenbroek was born on 14
March 1692 in Leiden, Holland, Dutch
A Dutch Mathematician. In 1745 he
discovered that charges can be built up
and stored in what he called as the
Leyden Jar named after the University of
Leyden he worked.
Leyden jar helped in understanding
Alessandro Volta was born in Como, Italy in
1745. In 1774, he was an Italian Physicist and
appointed as professor of physics at the
Royal School in Como.
In 1800 he developed the first practical
method of generating electricity by
inventing the battery.
In his battery he used a stack of silver and
zinc plates as the dissimilar materials and
separated them from each other.
A German physicist who discovered the law,
named after him, which states that
the current flow through a conductor is
directly proportional to the
potential difference (voltage) and inversely
proportional to the resistance.
In 1827, he discovered that different
conductors opposed the flow of change in
Ohm’s Law states that the voltage across
the conductor is a proportional to the
current passing through it. The unit
resistance is called Ohm (Ω).
Joseph John Thomson, is an English
Physicist always known as "J. J.," was born
in Manchester, England, on December 18,
1856. His fame derives primarily from his
discovery of the electron in 1897.
In 1897 he discovered the electron.
Combined with Rutherford's discovery of
the nucleus that contains positive protons
and experiment that measures the charges
of proton and electrons the charge of
