Exploring the Origins of Electric Vocabulary

The video explores the history of electric vocabulary, starting with Thales of Miletus and the term 'electron' for amber. It covers William Gilbert's and Charles Du Fay's contributions to understanding electrical phenomena. Benjamin Franklin's playful experiments led to the concept of electric batteries and the vocabulary we use today. J.J. Thomson's discovery of electrons revealed the true nature of electrical fluid, yet Franklin's terminology persists as conventional current.
