I-inductance iyiluphu evaliwe kanye nempahla yenani elibonakalayo. Lapho ikhoyili idlula isikhathi samanje, kwakheka induction ye-magnetic field in the coil, yona ikhiqize i-current eyenzelwe ukumelana namandla amanje ageleza kukhoyili. Lokhu kusebenzisana phakathi kwamanje kanye nekhoyili kubizwa ngokuthi i-inductance noma i-inductance ku-Henry (H) kususelwa kusosayensi waseMelika uJoseph Henry. Kuyipharamitha yesekethe echaza umthelela wamandla e-electromotive akhangwe kule khoyili noma kwenye ngenxa yokushintsha kwamandla ekhoyili. I-inductance yitemu elijwayelekile lokuzithokozisa kanye ne-mutual inductance. Idivaysi ehlinzeka nge-inductor ibizwa ngokuthi i-inductor.

Iyunithi ye-inductance
Njengoba inductance yatholwa usosayensi waseMelika uJoseph Henry, iyunithi ye-inductance ithi “Henry”, efushanisiwe ngokuthi uHenry (H).

Amanye amayunithi we-inductance yilawa: i-millihenry (mH), i-microhenry (μH), i-nanohenry (nH)

Ukuguqulwa kweyunithi ye-inductance
1 Henry [H] = 1000 millihenry [mH]

1 millihenry [mH] = 1000 microhenry [uH]

I-microhenry engu-1 [uH] = 1000 nanohenry [nH]
Isakhiwo sekhondatha esikalwa ngesilinganiso samandla e-electromotive noma i-voltage eyengelwe kukhondatha kuya kuzinga lokushintsha kwamandla amanje akhiqiza le voltheji. I-current steady ikhiqiza inkambu kazibuthe ezinzile, futhi i-current eshintshayo (AC) noma i-DC eguquguqukayo ikhiqiza inkambu kazibuthe eshintshayo, yona eyenza amandla e-electromotive ku-conductor kule nsimu kazibuthe. Ubukhulu bamandla e-electromotive obangwayo bulingana nezinga lokushintsha kwamandla amanje. Isici sokukala sibizwa ngokuthi i-inductance, eboniswa uphawu L, futhi ngo-henries (H). I-inductance iyisici seluphu evaliwe, okungukuthi lapho i-current ngokusebenzisa iluphu evaliwe ishintsha, kwenzeka amandla e-electromotive ukumelana noshintsho lwamanje. Le inductance ibizwa ngokuthi i-self-inductance futhi iyimpahla ye-loop evaliwe ngokwayo. Uma sicabanga ukuthi i-current ku-loop eyodwa evaliwe iyashintsha, amandla e-electromotive akhiqizwa kwenye iluphu evaliwe ngenxa yokungeniswa, futhi lokhu kufakwa kubizwa ngokuthi i-mutual inductance.
