Ponena za magalimoto omwe amawoneka m'moyo wathu watsiku ndi tsiku, magetsi achikhalidwe ayambanso kulowa mu nthawi ya magetsi a LED. Kuthamanga kwachitukukoku kumachitika makamaka chifukwa chogwiritsa ntchito zida zamphamvu kwambiri-LED katundu resistorspa magetsi a LED.
Pakadali pano, kugwiritsa ntchito kwa LED pakuwunikira kwamagalimoto kukuchulukirachulukira tsiku ndi tsiku, kuyambira pakuyatsa koyambira mkati mwagalimoto kupita kuzinthu zambiri monga nyali zakutsogolo ndi magetsi ophatikizika amchira. M'zaka zaposachedwa, nyali zamagalimoto a LED zakhala chisankho choyambirira komanso chokhazikika pamagalimoto ambiri, kaya ndi otsika kapena apamwamba.
LED katundu resistorszimagwira ntchito yofunika kwambiri polumikizana pakati pa magetsi apagalimoto ndi magetsi a LED. Ma LED load resistors amagwiritsidwa ntchito kwambiri pamagetsi a LED. Ma LED amagalimoto amafunikira kuwala kwakukulu, kupulumutsa mphamvu, kuteteza chilengedwe komanso kukhazikika, ndipo gwero la kuwala kwa LED limatha kufanana ndi mawonekedwe olemera ndi kusintha kwa mizere ya magetsi agalimoto. Zotsatirazi zitha kutsimikizira bwino magwiridwe antchito komanso mtundu wa zida zamphamvu zamphamvu za LED.
M'magalimoto ambiri,LED katundu resistorskukhala ndi makhalidwe a grooves kutentha kutentha, kukula kwazing'ono, mphamvu zambiri, kukana kutentha kwambiri, mphamvu zodzaza kwambiri, kukana nyengo, kulondola kwambiri, kukhazikika kwakukulu, mawonekedwe amphamvu a chimango, kuyika kosavuta ndi zina zabwino. Itha kugwira ntchito mokhazikika pamagalimoto osiyanasiyana, kupereka chitetezo chofunikira pazithunzi zamagalimoto, komanso kukulitsa moyo wautumiki wa LED.
