🎤Pronunciation
🌳Etymology
Origin
Discharge derives from Latin dis- (away) and carcare (to load), originally meaning 'to unload.' The term was metaphorically applied to electrical phenomena, comparing the release of electrical energy to the unloading of cargo. Tube comes from Latin tubus, meaning 'pipe' or 'hollow cylinder,' and was adopted to describe the glass vessel in which electrical discharge occurs.
Breakdown
dis- (away, apart) + charge (from carcare, to load) + tube (from Latin tubus, pipe). The compound describes a tubular vessel through which electrical discharge passes.
