Discovering Electricity

• Benjamin Franklin (1706-1790) – His kite experiment demonstrated that lightning is electricity. He also was the first person to use the terms positive and negative charge.

• William Thomson, Lord Kelvin (1824- 1907) –They calculated after a lot of mathematics that the lowest temperature possible for any state of matter to reach is -273° C. This relates to electricity because when objects are at very low temperatures, they become ‘super conductors’, meaning they can conducts large amounts of electricity.

• Thomas Seebeck (1770-1831) – He discovered thermoelectricity.

• Michael Faraday (1791-1867) – He worked on how electric currents work and was one of the most successful scientists in the field of electricity. His work helped scientists even one hundred years later. He was never set back by failure. He would say; "the failures are just as important as the successes." He felt failures also teach. The farad, the unit of capacitance is named in the honor of Michael Faraday.

• James Maxwell (1831- 1879) – He used Faraday’s work to turn it into a mathematical expression. The unit used for electromagnetism was named in his honor.

• Albert Einstein (1879 – 1955) – Arguably one of, if not the most famous, scientist of all time, Einstein proved that one gram of mass can be converted into an amount of energy. E=MC^2.


Discovering electricity could not be done without all of the work from these noted scientists and many others. There work all helped each other to excel in a related area.
