Dab tsi yog qhov yooj yim nyob ntawm capacitance:
Chav yooj yim ntawm capacitance: f (Fabkis), ntxiv rau qhov μ f (hom micro), pF (nqaij), muaj tseem yog ib tug sib piv nrog rau lwm tsawg zog, namely: nF (), vim tus tau txog lub capacitor no loj heev, ces peb pom feem ntau yog μ f, nF, pF chav nyob, tsis txhob f chav nyob.
Zoo ib yam kev cai rau hauv lub ntiaj teb, ntxiv rau 1 volt DC voltage rau capacitor, nws yuav muab tus nqi ntawd, rau lub capacitance ntawm tus capacitor (lub hwj huam nyob voltage), los ntawm qhov tsab ntawv c ntawd hais. Tej chav uas capacitance farad (f). Tsis tau muaj 1 volt DC voltage, piv txwv tias yog ib tug capacitor stores xwb ntawm 1 Coulomb, peev xwm yog teev ntawm 1, Farrah Farah nrog cov cim f, raws li muaj nyob rau hauv lub 1F = 1Q/V. Rau qhov xyaum, kev siv, cov capacitance ntawm tus capacitor yog feem ntau npaum li cas me dua tus 1 farad, feem ntau me me rau lwm, millifarad (mF), micro-qauv (μ f), nanofarad (nF), txoj cai lij choj (pF), lawv hu yog: 1 micro-yog ib tug ntawm li ntawm 10,000 leej Farah; txujci micro 1 txoj kev rau cov tawv nqaij ib leeg ntawm 10,000 siab sib npaug.
