Chofunika kwambiri, chotsutsana, chingamawoneke ngati zigawo zosavuta zomwe zili ndi zochepa, koma zotsutsana zili ndi mitundu yosiyanasiyana ya mawonekedwe ndi mawonekedwe .
Zowonetsera
Kutentha kwa joule ndi kutentha komwe kumapangidwa pamene panopo kudutsa kupyolera. Kawirikawiri kutentha uku ndi chinthu chofunika kwambiri pakusankha kukana kuonetsetsa kuti ntchito yodalirika, koma muzinthu zina, cholinga cha kukana ndicho kupanga kutentha. Kutentha kumapangidwa ndi kuyanjana ndi magetsi omwe akuyenda kupyolera mu conductor, kumakhudza maatomu ake ndi ions, zomwe zimapangitsa kutentha kupyolera mu kukangana. Zinthu zotentha zimagwiritsidwa ntchito pamagulu osiyanasiyana monga magetsi ndi mavuni, magetsi a magetsi, opanga khofi, komanso ngakhale kuteteza galimoto yanu. Nthawi zambiri amatha kutentha ndi magetsi kuti azionetsetsa kuti palibe chilichonse chimene chidzaperekenso kuntchito yoyenera yomwe ikufunikira kwambiri makamaka m'madzi otentha amadzi omwe amagwiritsa ntchito kutentha. Kuonjezerapo kuti ntchito yamakono yowonjezereka ikugwiritsidwa ntchito monga nichrome, nickel ndi chromium, zomwe zimakhala zothandiza kwambiri komanso zosagonjetsedwa.
Fuse
Makina okonzedweratu omwe amagwiritsidwa ntchito makamaka amagwiritsidwa ntchito ngati mafayilo osagwiritsidwa ntchito limodzi. Zinthu zoyendetsa fuseti zimapangidwa kuti zidziwononge zokha pokhapokha ngati pakali pano pakhomopo paliponse, podzipereka kuti zisawononge kuwononga ndalama zamagetsi. Ma fuses alipo ndi katundu wosiyanasiyana kuti apereke nthawi yofulumira kapena yowonongeka, nthawi zamakono komanso mphamvu zamagetsi, ndi mafunde otentha. Zimapezekanso pazinthu zingapo monga mafayilo a fomu omwe amagwiritsidwa ntchito pamagalimoto, magalasi omwe ali mkati mwa fuses, mafayiketi a fiberglass makasitomala, ndipo amapota fuses kuti atchule ochepa. Ma fuses omwe amagwiritsidwa ntchito pogwiritsa ntchito malowa amakhala osakwanira koma matekinoloje opangira mafakitale amatha kuchepetsa vuto kwa wogwiritsa ntchito kupeza ndi kubwezeretsa fuseti ndipo amagwiritsidwa ntchito pa zipangizo zamtengo wapatali komanso zamagetsi zosagwiritsidwa ntchito ndi wogwiritsira ntchito ndipo amatha kutenga ndalama zapamwamba zotengera mafasho .
Zizindikiro
Zotsutsa zimagwiritsidwa ntchito monga zithunzithunzi za ntchito zosiyanasiyana kuchokera ku magetsi kuti zikhale zowona. Kusintha kwa kukana kungayambitsidwe ndi zifukwa zambiri kuphatikizapo madzi ndi zina zamadzimadzi, chinyezi, kupweteka kapena kusinthasintha, komanso kutsekemera kwa mpweya muzinthu zowononga. Mwa kusankha zinthu zoyenera ndi zowakulungidwa, ntchito yamagetsi yotetezera imagwiritsidwa ntchito pofuna ntchito yapadera ndi chilengedwe. Masensa othawiritsira ntchito amagwiritsidwa ntchito monga gawo la masensa pa makina a polygraph kuti ayang'ane kutuluka kwa phunziro mu nthawi yeniyeni pamene akuyesa. Pamene nkhaniyo ikuyamba kutuluka thukuta, chojambulira chimakhudzidwa ndi kusintha kwa chinyezi ndipo chimapereka kusintha koyeso kwa kukana. Magetsi oyendetsa mpweya amatha kugwira ntchito mofanana, ndi kupezeka kwakukulu kwa mpweya womwe ukuchititsa kusintha kwa kukana kwa sensa. Malinga ndi kapangidwe kansangamsanga, kudzidzimitsa kungatheke pogwiritsa ntchito mawu omwe akuwonekera pakali pano kuti achotse zonse zomwe zimatulutsa.
Kwa masenema omwe amasintha pang'ono pokhaponse pazitsulo zonsezi, makina ogwiritsa ntchito mlatho amatha kugwiritsidwa ntchito kuti apereke zizindikiro zosasinthika zoyeza molondola ndi kukulitsa.
Kuwala
Thomas Edison anakhala zaka zambiri akufunafuna zinthu zomwe zingapangitse kuwala kokhazikika magetsi. Ali panjira, adapeza mitundu yambiri yopangidwa ndi zipangizo zomwe zingapangitse kuwala ndikudziwotcha pomwepo, monga fuse yomwe imadzipereka yokha. Potsirizira pake, Edison adapeza zinthu zoyenera komanso zojambulazo zomwe zinapanga kuwala kosalekeza komwe kunakhala chinthu chachikulu kwambiri komanso chofunika kwambiri chotsutsa kwa zaka zambiri. Masiku ano pali njira zina zomwe zimagwiritsidwa ntchito popanga mawotchi atsopano ndipo zina zimakhalabe zopangidwa monga mababu a halogen. Magetsi osokoneza bongo akutsogoleredwa ndi CCLF ndi magetsi a LED, omwe ali amphamvu kwambiri kuposa mababu a kuwala.
