galvanic
- Adjective:
- Relating to or producing a direct electric current, especially from a chemical reaction: This meaning describes something that generates electricity through chemical action, such as in a battery.
- Suddenly and dramatically stimulating, exciting, or energizing: This figurative meaning describes something that has a shockingly powerful, thrilling, or revitalizing effect, as if by an electric current.
Pertaining to electricity from chemical action:
- The scientist explained the principle of a galvanic cell.
- A galvanic reaction occurs between two dissimilar metals in an electrolyte.
Figurative: Shockingly stimulating or energizing:
- The coach's halftime speech had a galvanic effect on the team, who came back to win the game.
- Her galvanic performance captivated the entire audience.
"Galvanic response": In psychology or physiology, this can refer to a measurable change in the electrical properties of the skin (like skin conductance) due to emotional arousal.
- The polygraph test measures galvanic skin response as an indicator of stress.
"Galvanic corrosion": A technical term for accelerated corrosion that occurs when two different metals are electrically connected in a corrosive environment.
- Using a stainless steel bolt on an aluminum plate can cause galvanic corrosion.
Galvanize (verb): To shock or excite someone into taking action; also, to coat iron or steel with a protective layer of zinc.
- The tragic event served to galvanize public opinion.
- The steel beams were galvanized to prevent rust.
Galvanism (noun): An old-fashioned term for electricity produced by chemical action; also, the therapeutic application of such electricity.
- Early experiments in galvanism were conducted by Luigi Galvani.
- Electric: Producing or charged with electricity; thrilling.
- Voltaic: Another technical adjective for electricity produced by chemical action (named after Alessandro Volta).
- Electrifying: Causing a sudden sense of excitement or thrill.
- Stimulating: Encouraging or arousing interest or enthusiasm.
- Sedative: Tending to calm or soothe.
- Dull: Lacking interest or excitement.
- Deadening: Causing a loss of force, vitality, or sensation.
The two primary meanings are connected historically. The term originates from Luigi Galvani's 18th-century experiments with "animal electricity," where he made frog muscles twitch using metal. The literal meaning (electric current from chemistry) comes directly from this scientific context. The figurative meaning (a jolt of energy or excitement) is a metaphorical extension, comparing a sudden emotional or motivational surge to an electric shock.
- affected by emotion as if by electricity; thrilling
- gave an electric reading of the play
- the new leader had a galvanic effect on morale
- pertaining to or producing electric current by chemical action
- a galvanic cell
- a voltaic (or galvanic) couple
