How they found electricity????

BENJAMIN FRANKLIN

In 1752, Franklin proved that lightning and the spark from amber were one and the same thing. This story is a familiar one, in which Franklin fastened an iron spike to a silken kite, which he flew during a thunderstorm, while holding the end of the kite string by an iron key.

When lightening flashed, a tiny spark jumped from the key to his wrist. The experiment proved Franklin's theory, but was extremely dangerous - he could easily have been killed.

Michael Faraday

In 1831, Faraday found the solution. Electricity could be produced through magnetism by motion. He discovered that when a magnet was moved inside a coil of copper wire, a tiny electric current flows through the wire. Of course, by today's standards, Faraday's electric generator was crude (and provided only a small electric current), but he had discovered the first method of generating electricity by means of motion in a magnetic field.

The credit for generating electric current on a practical scale goes to the famous English scientist, Michael Faraday. Faraday was greatly interested in the invention of the electromagnet, but his brilliant mind took earlier experiments still further. If electricity could produce magnetism, why couldn't magnetism produce electricity?

OHM

George Simon Ohm, a German mathematician and physicist, was a college teacher in Cologne when in 1827 he published, "The Galvanic Circuit Investigated Mathematically". His theories were coldly received by German scientists, but his research was recognized in Britain and he was awarded the Copley Medal in 1841. His name has been given to the unit of electrical resistance.

Voltage = Current x Resistance

From where electricity came

ELECTRICITY

The science of electricity has its roots in observation, known in 600 BC that a rubbed piece of amber will attract a bit of straw.

Study of magnetism goes back to the observation that certain naturally occurring stones attract iron.

The two sciences were separate until 1820 when Hans Christian Oersted saw the connection between them…an electric current in a wire will affect a compass needle.

Around 600 BC Greeks found that by rubbing a hard fossilized resin (Amber) against a fur cloth, it would attract particles of straw. This strange effect remained a mystery for over 2000 years.

Around 1600, William Gilbert, a physician who lived in London at the time of Queen Elizabeth I and Shakespeare, studied magnetic phenomena and demonstrated that the Earth itself was a huge magnet, by means of his "terrella" experiment. He also studied the attraction produced when materials were rubbed, and named it the "electric" attraction. From that came the word "electricity" and all others derived from it.

During the 1800s it became evident that electric charge had a natural unit, which could not be subdivided any further, and in 1891 Johnstone Stoney proposed to name it "electron."

When J.J. Thomson invented the particle which carried that charge, the name "electron" was applied to it. He won the Nobel Prize in 1906 for his discovery.
