I-Resistor iyingxenye kagesi nje yokudala ukudala ukumelana nokugeleza kukagesi kwamanje. Cishe wonke amanethiwekhi kagesi nemibuthano ye-elekthronikhi angatholakala. Ukumelana kulinganiswa kuma-ohms. I-ohm ingukumelana okwenzeka lapho i-ampere yamanje ye-amperere idlula ngokuphikisana ne-volt eyodwa yehla ngaphesheya kwezindawo zawo. Okwamanje kulingana namandla kagesi ngaphesheya kweziphetho ze-terminal. Lesi silinganiso simelelwa yiUmthetho ka-Ohm:

Ukumelana kusetshenziselwa izinhloso eziningi. Izibonelo ezimbalwa zifaka phakathi ukudilizwa kukagesi kwamanje, ukuhlukaniswa kwamandla kagesi, ukukhiqizwa kokushisa, ukufana kanye nokulayisha amasekethe, ukuthola inzuzo, kanye nokulungisa isikhathi. Ziyatholakala ngokuthengisa ngamanani wokumelana ngaphezu kwebanga elingaphezu kwama-oda ayisishiyagalolunye ngobukhulu. Zingasetshenziswa njengamabhuleki kagesi ukuqeda amandla e-kinetic kusuka ezitimeleni, noma kube yincane kune-millimeter skwele ye-elekthronikhi.

Amanani Wokumelana (Amanani Athandwayo)
Ngawo-1950s lapho ukukhiqizwa okwengeziwe kwabaphikisayo kwakha isidingo samanani wokumelana ajwayelekile. Ububanzi bamanani okumelana buhlelwe ngamanani abizwa ngokuthi athandwayo. Amanani athandwayo achazwa ku-E-Series. Ku-e-series, lonke inani lamaphesenti athile aphakeme kunangaphambili. I-E-Series ehlukahlukene ikhona ngokubekezelelana okuhlukile.

Ukumelana Nezinhlelo
Kunokuhlukahluka okukhulu emikhakheni yezicelo zabameli; Kusuka ezingxenyeni eziqondile kumadivayisi wedijithali, kuze kube amadivaysi okulinganisa amanani abonakalayo. Kulesi sahluko izinhlelo eziningana ezithandwayo zibaliwe.

Ukumelana nochungechunge nokufana
Emibuthanweni kagesi, ukumelana kuvame ukuxhumeka kakhulu ochungechungeni noma ngokufana. Umklami wesifunda angahle ahlanganise abaphikisi abaningana ngamanani ajwayelekile (i-e-Series) ukufinyelela inani elithile lokumelana. Okokuxhumana kochungechunge, okwamanje ngokusebenzisa ukumelana ngakunye kuyafana futhi ukumelana okulinganayo kulingana nesamba sabamelana nathi ngakunye. Ngokuxhumana okuhambisanayo, amavoluti ngokumelana ngakunye kuyafana, futhi ukuphambuka kokuphikiswa okulinganayo kulingana nenani lamanani angenamkhawulo kubo bonke abamelana nabesilisa. Kulezi zihloko zimelana nokufana nochungechunge incazelo eningiliziwe yezibonelo zokubalwa inikezwa. Ukuxazulula amanethiwekhi ayinkimbinkimbi kakhulu, kungasetshenziswa imithetho yesekethe yeKirchHoff.

Ukukala ugesi wamanje (i-shunt restion)
Amanje kagesi angabalwa ngokukala i-voltage Drop phezu kokuphikiswa okunembile nokumelana okwaziwayo, okuxhunyiwe ochungechungeni nomjikelezo. Okwamanje kubalwa ngokusebenzisa umthetho ka-Ohm. Lokhu kubizwa ngokuthi i-ammeter noma i-shunt resistor. Imvamisa lokhu kungukuphamba okuphezulu kwe-maningaganin ngenani eliphansi lokumelana.

APSASA OF LEDS
Izibani ze-LED zidinga okukodwa okusebenzayo ukuze zisebenze. Okwamanje okuphansi kakhulu ngeke kukhanyiselwe i-LED, kuyilapho kungenzeka kakhulu kungashisa idivaysi. Ngakho-ke, zivame ukuxhumeka kuchungechunge nabenkolo. Lokhu kubizwa ngokuthi ukumelana kwe-ballast futhi kulawulwe kabusha amanje esekethelweni.

Blower motor Resistor
Ezimweni zohlelo lokungena komoya kuthathwa ngumthandi oqhutshwa yimoto ye-blower. Kusetshenziselwa ukumelana okhethekile ukulawula isivinini sabalandeli. Lokhu kubizwa ngokuthi ukumelana kwezimoto okuqhuma. Imiklamo ehlukene iyasetshenziswa. I-Design Enye uchungechunge lwe-usayizi ohlukene we-wirewound ijubane lakuleli ngalinye. Omunye umklamo ufaka umjikelezo ohlanganiswe ngokuphelele ebhodini lesekethe ephrintiwe.
