William Gilbert was the accredited father ofthe science of electricity and magnetism.
William Gilbert first coined the term
"electricity" from the Greek word for amber.
He was also the first person to use the terms
electric force, magnetic pole, and electric
attraction.
William Gilbert was a pioneer of the
experimental method and the first to explain
the magnetic compass.

Edison set up the first commercial
research laboratory.
He invented the first successful
incandescent electric bulb, the
phonograph, the movie projector, the
carbon telephone transmitter, andeventually held 1,093 U.S. patents.
His parallel skill at commercializing his
inventions made the wizard of Menlo
Parka wealthy man.
Edison is famous for saying, Genius is
one per cent inspiration, ninety-nine per
cent perspiration.

Nikola Tesla was born in 1856 in
Smiljan Lika, Croatia.
Tesla invented fluorescent lighting,
the Tesla induction motor, the Tesla
Coil.
He developed the alternating current
(AC) electrical supply system that
included a motor and transformer,
and 3-phase electricity.
The Tesla coil, invented in 1891, is
still used in radio and television sets
and other electronic equipment.Nikola Tesla

Andre Marie Ampere is best known
for defining a way to measure theflow of current, which was namedafter him, the Ampere.
He also laid the foundation for thescience of electrodynamics.
He expalined a way to measure thestrength of a magnetic field inrelation to an electric current,known as Ampere's theorem.
Ampere's law is a rule that dealswith the mutual interaction ofcurrent-carrying wires.

Anders Celsius, a Swedish astronomer,
physicist and mathematician who isfamous for the temperature scale he
developed.
Celsius' fixed scale for measuring
temperature defines zero degrees as thetemperature at which water freezes, and
100 degrees as the temperature at which
water boils.
This scale, an inverted form of Celsius'original design, was adopted as the
standard and is still used in almost all
scientific work.

Michael Faraday is a chemist and
physicist.
He isolated benzene.
He proposed two laws on
electromagnetic induction, later calledas faradayslaws.
This discovery paved the way for
changing mechanical energy into
electrical energy.
The unit for capacitance is farad,
named after him for his contribution
in science. Michael Faraday

James Prescott Joule was Born in
Salford, England in 1818.
He stated a law, now called Joule's
Law, that heat is produced in an
electrical conductor.
The International unit of energy, the
joule, is named in his honor.
He is also one of two scientists whostated Law of conservation of
energy.

Georg Simon Ohm was Born inErlangen, Germany.
He discovered the mathematical lawof electric-current called "Ohm's
Law."
Simply represented as V I
The ohm, a unit of electrical
resistance, is equal to that of aconductor in which a current of oneampere is produced by a potential of
one volt across its terminals.Georg Simon Ohm

James Clerk Maxwell, an English
scientist, developed a scientific theoryto explain electromagnetic waves.
He noticed that electrical fields and
magnetic fields can couple together to
form electromagnetic waves.
He also states that An electromagnetic
wave exists when the changing
magnetic field causes a changing
electric field, which then causes another
changing magnetic field, and so on
forever.

Charles-Augustin de Coulomb, aFrench physicist best known for theformulation of coulumbslaw.
It states that the force between twoelectrical charges is proportional to the
product of the charges and inverselyproportional to the square of thedistance between them.
Coulumbic force is one of theprincipal forces involved in atomic
reactions.
The coulomb, SI unit of electriccharge, was named after him.

Erest Warner von Siemens made
outstanding contributions to the
expansion of electrical engineering and is
therefore known as the founding father of
the discipline in Germany.
He independently discovered the
dynamo-electrical principle and
developed interest in the growth of the
self-excited dynamo and electric-traction.
In 1880 he designed the worlds first
electric elevator.
For his contribution in physics, siemen is
named as unit for conductance.

Isaac Newton was English mathematical
and physicist, widely known for hisoutstanding contributions to physics,
mathematics and optics.
He also invented the calculus and
formulated the three laws of motion and
the universal theory of gravitation.
Newton proved that sunlight is the
combination of several colors.
Newton is the unit of force named after
him for his discoveries. Isaac Newton

Watt was a Scottish inventor .
His fundamental improvements
to the steam engine led to the
widespread use of steam power
in industry.
Watt is the unit of power.
The watt unit is named after
James Watt
