Ntchito yolumikizira: kugwiritsa ntchito mphamvu yamagetsi
Nthawi zambiri amagwiritsidwa ntchito ndi njira ziwiri zotsatirazi zotumizira mphamvu: zoperekedwa kumayendedwe apamwamba kwambiri munthawi yomweyo kukhudzana ndi kukhudzana ndi ma polygonal chizindikiro.Aliyense wa iwo ali ndi ubwino ndi kuipa kwake.
Pali kusiyana kuwiri pakati pa kufala kwa mphamvu ndi kufalitsa chizindikiro.Zikuwonekeranso kuti zimagwiritsidwa ntchito popereka mafunde apamwamba.Zomwe zimafalitsidwa ndi chizindikiro nthawi zambiri sizidutsa 1 ampere, ndipo sizidutsa ma amperes angapo nthawi zambiri, ndipo zomwe zimafalitsidwa ndi mphamvu zimatha kufika makumi kapena mazana a amperes.Mfundo ndi kuwonjezeka kwa kutentha chifukwa cha kutentha kwa Joule komwe kumachitika chifukwa cha panopa.Kutentha kwa Joule komwe kumapangidwa panthawi yolumikizana ndi ma sign ndi ofanana ndi kutentha kozungulira.M'malo mwake, chiŵerengero cha kufalitsa mphamvu chimachokera ku kuwonjezeka kwa kutentha, ndipo kuwonjezeka kwa kutentha kumapanga chiŵerengero chofananira panopa.Kuwonjezeka kwa kutentha kwa madigiri 30 nthawi zambiri kumagwiritsidwa ntchito ngati chiŵerengero chamakono.
Choncho, kuti mukwaniritse chiwerengero chamakono ndi zofunikira zokhazikika za ntchitoyi, m'pofunika kulamulira kutentha kwa Joule.Izi zimafuna kulingalira za kufalikira kwa chizindikiro pokonzekera komanso kufalitsa mphamvu.Makamaka kwa ma terminals okhala ndi kukana kwakukulu, kutentha kwa Joule ndi chinthu choyambirira, ndipo ndikofunikira kuchepetsa kutsika, komanso kukana kwa malo olumikizirana nawo kuyeneranso kuchepetsedwa kukhala otsika kuti achepetse kutentha komwe kumapangidwa.Kuchokera pamawonekedwe azinthu zosankhidwa, sankhani materminal okhala ndi ma conductivity apamwamba kapena malo okulirapo kuti muchepetse kukana.Kuphatikiza apo, kuwonjezera mphamvu yotumizira kapena kukulitsa malo olumikizirana nawo kungachepetsenso kukana kwa ena.
