Usayizi we-inductance unqunywa ububanzi be-inductor, inani lokujika, kanye nempahla ye-intermediate medium. Iphutha phakathi kwe-inductance yangempela kanye nevelu le-inductance ibizwa ngokuthi ukunemba kwe-inductance. Khetha ukunemba okufanele ngokwezidingo zangempela zokugwema ukumosha okungadingekile.

Ngokuvamile, i-inductance esetshenziselwa i-oscillation idinga ukunemba okuphezulu, kuyilapho i-inductance esetshenziselwa ukuhlanganisa noma ukuminyanisa idinga ukunemba okuphansi. Kwezinye izikhathi ezidinga ukunemba okuphezulu kwe-inductance, ngokuvamile kuyadingeka ukuyisonga ngokwayo futhi uyihlole ngethuluzi, ngokulungisa inani lokujika noma Ukuma kwengqikithi kazibuthe noma ingqikithi yensimbi ku-inductor iyabonakala.

Iyunithi eyisisekelo ye-inductance nguHenry, efushanisiwe njengoHenry, emelwe ngohlamvu "H". Ezisetshenziswa ezingokoqobo, i-millihenry (mH) noma i-microhenry (μH) ngokuvamile isetshenziswa njengeyunithi.

Ubudlelwano phakathi kwabo yilokhu: 1H=103mH=106μH. I-inductance iboniswa ngendlela evamile eqondile noma indlela evamile yombala. Ngendlela eqondile ejwayelekile, i-inductance iphrintiwe ngokuqondile ku-inductor ngendlela yombhalo. Indlela yokufunda inani ifana neye-chip resistor.

Indlela yekhodi yombala ayisebenzisi nje indandatho yombala ukukhombisa inductance, futhi iyunithi yayo i-microhenry (μH), i-inductance emelwe indlela yekhodi yombala inokumelana okukhulu kunekhodi yombala, kodwa incazelo yendandatho ngayinye yombala kanye indlela yokufunda ukubaluleka kagesi konke Kuyafana nokumelana nendandatho yombala, kodwa iyunithi ihlukile.

Isici sekhwalithi simelelwa uhlamvu Q. Q ichazwa njengesilinganiso sokusabela kwe-inductive okwethulwa ikhoyili ekumelaneni kwe-DC kwekhoyili lapho ikhoyili isebenza ngaphansi kwefrikhwensi ethile ye-voltage ye-AC. Uma iphezulu inani le-Q, iphakamisa ukusebenza kahle kwe-inductor.

I-current elinganiselwe ibizwa nangokuthi i-nominal current, okuyinani eliphezulu elivumelekile elivunyelwe nge-inductor, futhi ingenye yemingcele ebalulekile okufanele inakwe lapho usebenzisa i-inductor.

Ama-inductance ahlukene anezilinganiso ezihlukene zamanje. Lapho ukhetha i-inductor, qaphela ukuthi i-inductor yangempela egeleza kuyo akufanele idlule inani layo lamanje elilinganiselwe, ngaphandle kwalokho i-inductor ingase iphele.
