Indlela yokuthola amandla ezimweni ezahlukene?

Ekuphileni, ngezinye izikhathi kunezimo lapho kunesidingo esiphuthumayo ukuxazulula inkinga ehlobene nokubukisa kanjani ukuthola amandla, okungukuthi, ukubaluleka elihlobene ne imikhakha yomsebenzi kanye nesikhathi. Le sethingi ibalulekile ngoba ikuvumela ukuhlonza amagugu amaningi. Ngokwesibonelo, kungase kube lula ukubala isikhathi lapho uzobe wenza umsebenzi kusengaphambili. Wabuye uchaza, okubandakanya Yiqiniso, ukusebenza izinhlobo ezahlukene izinjini. Ngesisekelo lesi silinganiso kunganqunywa, isibonelo, petrol. Lokho, kubalulekile, kokubili physics kanye nasemnothweni. Ngakho-ke, isinqumo nezindaba ezihlobene nendlela yokuthola amandla, sinokubaluleka okukhulu okusebenzayo kanye esisebenzayo.

amayunithi

Evamile, amandla iyunithi zingahlukaniswa zibe eluhlelweni kanye non-letindzala. Esimweni sokuqala, it Watts (W noma W) futhi uchungechunge zesi futhi submultiples, abizwa zazo akhiwa ngokungeza Isiqalo ukuba ngesisekelo ngenhla. Ngokwesibonelo, kilowatts - kuyinto eziyinkulungwane Watts. On ezingeni ngokomzimba, lolu phiko ephawula umsebenzi okusamele wenziwe phakathi nesikhathi sokuphumula. the obanzi kunayo okuthiwa "amahhashi" phakathi kwabangewona uhlelo amayunithi. Lokhu kungenxa yokuthi amandla iningi yangaphakathi omlilo injini namuhla kukalwa kulezi amayunithi. Ubudlelwano elandelayo phakathi kwawo - omunye amahhashi kuyinto 735 watt nengxenye. Uma sinqume kuzilinganiselo lapho kukalwa ipharamitha ngokomzimba, phendula umbuzo mayelana nendlela ukuthola amandla i-physics kanye electronics.

physics

Amandla e-physics kuxhumene ngqo nomunye ipharamitha ezibalulekile - emsebenzini. Ngenxa inkomba kudingekile ukhonza isikhathi. Ngenxa yalokho, amandla kungenziwa kunqunywa umsebenzi owenziwa isikhathi esithile. Yingakho ifomula ngoba amandla kubalwa, okuyinto kanje: N = A / t. Kulesi ifomula, notation ezilandelayo: N - amayunithi amandla ohlelweni, A - umsebenzi, ulinganiswa Joules, t - isikhathi ngemizuzwana. Ngakho, A sikhombisa lemali edingekayo emsebenzini, N ibonisa ukuthi ingxenye yayo, ukuze kwenziwe wezindleko, ukuze ube nesikhathi ukwenza kube phezu t isikhawu.

Ihluzo Elingafaki Ukuqoka

Ngo ubunjiniyela kagesi, ngokungafani physics, konke kulula kakhulu. Bobabili ngemcondvo kanye practice. Kwakucatshangwa ipharamitha efanayo kunqunywa umkhiqizo lamanani ethize zamanje kanye voltage. Okungukuthi, abangabantwana Ifomula P = U * I. lapho P - kuyinto amandla yonke wattage efanayo. U - voltage, ulinganiswa volts, futhi mina - samanje amperes. Ifomula jikelele, leyo nkulumo kunikezwa isebenza kokubili DC futhi AC. Ngalo ungakwazi kalula ukunquma inani amandla kunoma iyiphi idivayisi. Ngaphezu kwalokho, ngo-umkhuba, kudivayisi eyodwa - imitha. Okokuqala, izilinganiso parallel ichaze voltage, bese serial - zamanje. Ngokuvamile, ngale ndlela ungakwazi ukuthola impendulo yombuzo kanjani ukuthola amandla injini. Kungenjalo, ukufundwa can ngoba isicelo wattmeter. Kodwa lokhu imishini sokulinganisa eqolo, ngenxa yalesi sizathu, okwamanje okwandile. Kodwa multimeters kakade babe yingxenye yezimpilo zethu futhi nsuku zonke ziya ziba mandla asetshenziswayo. Baphinde babe yizinhlobonhlobo omkhulu esihlukanisa ngokumelene kwamanye amadivaysi, okuyinto ezikhethekile kakhulu.

isifinyezo

Isihloko kusiza ukuphendula umbuzo kanjani ukuthola amandla yemvelo noma kwezobunjiniyela kagesi. Ngamagama ezihambisana nawo, electronics Lokhu ubeka lula kakhulu ukuthola ukuthi iyini. Kodwa uma ufuna ngokusebenzisa yesimanje izindlela lobuchwepheshe ongaxazulula yimuphi umsebenzi, kungakhathaliseki ukuthi ngikuziphi sithombe.
