Electricity
Electricity is the physical phenomenon associated with electric charge, a fundamental force that has been harnessed to power virtually every aspect of modern civilization.
Understood only in fragments through scattered 18th-century experiments, this fundamental physical phenomenon was gradually unified into a coherent science that would go on to power nearly every aspect of the modern world.
Early Experimental Foundations
Systematic study of electricity began in the 18th century with figures including Benjamin Franklin, whose famous kite experiment demonstrated the electrical nature of lightning.
Faraday's Foundational Discoveries
Michael Faraday's 19th-century discovery of electromagnetic induction demonstrated how mechanical motion could generate electric current, providing the foundation for modern electricity generation.
The War of the Currents
The late 19th century saw a significant commercial dispute known as the "War of the Currents," between advocates of alternating current and direct current systems, ultimately won by alternating current.
Powering Modern Civilization
Electricity now underlies virtually every aspect of modern life, from lighting and communication to computing and transportation, representing one of history's most transformative technological developments.
