Aliyense mwina amadziwa bwino za mita yamagetsi. Masiku ano, mita yanzeru nthawi zambiri imagwiritsidwa ntchito poyesa ndikulipira magetsi apakhomo. Mukayang'anitsitsa, mupeza kuti pali chizindikiro 5 (60) cholembedwa pamalo owonekera a mita yamagetsi.

Mwachitsanzo, chizindikiro chomwe chili mu bwalo lofiira pachithunzi pamwambapa: 5 (60) A. Poyang'ana gawoli, tikudziwa kuti lalembedwa ngati lamagetsi, ndiye kodi pali ubale wotani pakati pa mafunde awiriwa? Kodi chimachitika n'chiyani pamene mphamvu yamagetsi yapitirira? Tiyeni tikambirane za zomwe mafunde awiriwa amatanthauza malinga ndi mabulaketi akunja (5) ndi mkati mwa mabulaketi (60).
Mphamvu mu mabulaketi
Mphamvu yamagetsi yomwe ili m'mabokosi - 60A mu chitsanzo, ikutanthauza mphamvu yamagetsi yomwe imayesedwa kwambiri pa mita yamagetsi. Mosiyana ndi zida zina, mphamvu yamagetsi yomwe imayesedwa ya mita yamagetsi imakhudzidwa kwambiri ndi zinthu zachilengedwe, kotero malire ena nthawi zambiri amasiyidwa ikachoka mufakitale - mphamvu yamagetsi yeniyeni yomwe imayesedwa ndi 120% ya mphamvu yamagetsi yomwe yalembedwa. Chifukwa chake, ngati nambala yomwe ili m'mabokosi ndi 60, mphamvu yake yayikulu yomwe imayesedwa ndi 72A - ngati si malo ovuta kwambiri, mphamvu yamagetsi yomwe imayesedwa sidzafika pa 20%. Chifukwa chake, mphamvu yamagetsi yayikulu yomwe imayesedwa ya mita yomwe yalembedwa ndi 60A nthawi zambiri imakhala pafupifupi 66A pakugwiritsa ntchito kwenikweni.
Kodi chimachitika n’chiyani mtengo uwu ukapitirira? Yankho lake ndi lolakwika poyeza - mwina zambiri, mwina zochepa.
Mabulaketi akunja amakono
5 kunja kwa mabulaketi pano amatchedwa mphamvu yoyambira, yomwe imatchedwanso mphamvu yowerengera. Imatsimikiziridwa ndi mphamvu yoyambira ya mita yamagetsi - mtengo wocheperako wamagetsi womwe umalola mita yamagetsi kuzungulira mosalekeza ndikuyesa mosalekeza. Mphamvu yoyambira ya mita yanzeru ndi 0.4% ya mphamvu yovotera. Izi zikutanthauza kuti, mita yokhala ndi mphamvu yovotera ya 5A idzalipiridwa bola mphamvu mu dera ifike pa 0.02A ikagwiritsidwa ntchito. Padzakhala chiŵerengero pakati pa mphamvu yovotera ndi mphamvu yovotera yapamwamba kwambiri, monga 5 (60) A, yomwe ndi ubale wa nthawi 4. Chiŵerengerochi chimatchedwa "m'lifupi mwa katundu". Kawirikawiri, pali nthawi 2, nthawi 4, nthawi 6, nthawi 8 kapena kupitirira nthawi 10 - kukula kwa katundu kukakhala kwakukulu, mulingo waukadaulo umakhala wolimba, ndipo mtengo wa mita udzakhala wapamwamba mwachibadwa.
Chifukwa chake, manambala omwe ali kunja kwa mabulaketi sakugwirizana kwenikweni ndi momwe wogwiritsa ntchito amagwiritsira ntchito—zochuluka kapena zochepa kuposa mtengo uwu sizikhudza kuyeza kwa mita. Pali zinthu ziwiri zomwe zimakhudzidwa makamaka ndi kuyeza kwa mita: mtengo wa mita (wokhudzana ndi kukula kwa katundu) ndi mphamvu yoyambira (yowerengedwa ndi mphamvu yoyeza).
