The science of measuring electric current using a galvanometer; the practice of detecting and quantifying electrical current.
From galvano- (galvanism) + -metry (measurement). This technical term emerged in the early 1800s as scientists developed systematic methods to measure electrical phenomena that Galvani had discovered.
Galvanometry was literally the technology that proved electricity wasn't just a weird party trick—it transformed electricity from magic into measurable science that engineers could use to build things.
