En Kondensator er et lite "batteri" som brukes til å lagre strøm for en kortere periode. Kondensatorer er ikke reelle batterier, da de ikke kan gi en elektronstrøm uten først å ha lagret elektroner. Et batteri derimot gir strøm basert på forskjellige stoffers evne til å lage en elektronstrøm, mens en kondensator lagrer strøm basert på en halvleders evne til å lagre elektroner. Kapasiteten til en kondensator måles i F, Farad. I elektronikk brukes kondensatorer på mellom 0,47µF og 2200µF.
