From Wikipedia: Originally, galvanization was the administration of electric shocks (in the 19th century also termed Faradism , after Michael Faraday). It stemmed from G
…alvani's induction of twitches in severed frogs' legs, by his accidental generation of electricity. This archaic sense is the origin of the meaning of galvanic when meaning "affected/affecting, as if by a shock of electricity; startled". [1] Its claims to health benefits have largely been disproven, except for some limited uses inpsychiatry in the form of electroconvulsive therapy (ECT). Later the word was used for processes of electrodeposition. This remains a useful and broadly applied technology, but the term "galvanization" has largely come to be associated with zinc coatings, to the exclusion of other metals. ( Full Answer )
