Plural of capacitance, a measure in physics of how much electrical charge a material or device can store.
From French capacité and Latin capacitas meaning 'capability' or 'ability to hold,' with the scientific suffix -ance added to create the technical term.
Capacitors are hiding in almost every electronic device you own, silently storing tiny amounts of electrical energy—without them, your phone, computer, and even your watch wouldn't work!
