Indlela ukufumana amandla kwiimeko ezahlukeneyo?

Kubomi, maxa wambi kukho iimeko xa imfuno engxamisekileyo ukusombulula ingxaki ezinxulumene ne yokufumana njani amandla, oko kukuthi, ixabiso ezinxulumene iindidi zomsebenzi kunye nexesha. Olu seto emzimbeni kubalulekile kuba kuvumela ukuba ukubona amanani amaninzi. Umzekelo, kunokuba lula ukubala ixesha apho kuya kwenziwa khona umsebenzi kwangaphambili. Kwakhona uchaza, okubandakanya, Kakade, ukusebenza iintlobo ezahlukeneyo ze-injini. Ngokwesiseko eli xabiso nako ukumiselwa, umzekelo, amafutha. Oko kukuthi, kubalulekile, bobabini ngenxa zemvelo kuqoqosho. Ngoko ke, isigqibo ngemiba enxulumene yokufumana njani amandla, sibaluleke kakhulu eluncedo and practical.

units

Ngokuqhelekileyo, iyunithi amandla lungohlulwa lube systemic and non-zenkqubo. Kwimeko yokuqala, oko watts (W okanye W) kunye uthotho iziphindwa kunye submultiples, izihionipho apho akhiwa ngokudibanisa isimaphambili kule isiseko ngasentla. Umzekelo, kilowatts - ngu eliwaka watts. Kwinqanaba elibonakalayo, le yunithi luphawu umsebenzi ekufuneka wenziwe ngexesha lekhefu. obanzi kakhulu kangangokuba-ebizwa ngokuba "Injini" phakathi kweeyunithi non-nkqubo. Oku kungenxa yokuba ngamandla uninzi injini yokutsha lwangaphakathi namhlanje ulinganiswa kwezi yunithi. Ubudlelwane zilandelayo phakathi kwabo - omnye enjini i-watt 735 enesiqingatha. Xa isigqibo phezu units apho ilinganiswa i parameter ngokwasemzimbeni thina, ukuphendula umbuzo malunga yokufumana njani amandla physics kanye ngombane.

physics

Power physics inxulumene ngqo kwenye parameter ebalulekileyo - umsebenzi. Njengoko lwesalathisi kuyimfuneko ikhonza ixesha. Ngenxa yoko, amandla aokusetyenziswa kumiselwa umsebenzi wenziwa kangangexesha elithile. Ngenxa yoko Ifomula amandla zokubala, elolu hlobo lulandelayo: N = A / t. Kule formula, le notation ilandelayo: N - units amandla kule nkqubo, A - umsebenzi, kulinganiswa kwi ziijowule, t - ixesha kwimizuzwana. Ngoko ke, A ibonisa imali efunekayo zomsebenzi, kunye N ibonisa ukuba inxalenye yaso, ukuba kwenziwe le lilonke, ukufumana ixesha ukuze kube phezu t lekhefu.

ikharakhtha eyahlulayo

Electrical Engineering, ngokungafaniyo physics, yonke into lula kakhulu. Zombini ithiyori kwaye practice. Enyanisweni, i parameter efanayo emiselwe imveliso iinqobo ezithile olukhoyo kunye ombane. Oko kukuthi, ifomyula P = U * I. apho P - lingamandla ukuba zonke ombane efanayo. U - ombane, kulinganiswa e volts, yaye mna - yangoku amperes. Ifomula sikhona yonke, ukuba ibinzana unikwa isemthethweni zombini DC ne AC. Ngalo lula ukufumana isixa amandla nasiphi na isixhobo. Ngaphezu koko, xa kusenziwa, isixhobo enye kuphela - imitha. Okokuqala, imilinganiselo ukufana ukuchaza ombane; kwandule ke serial - yangoku. Ngokufuthi, le ndlela uyakwazi ukufumana impendulo yombuzo yokufumana njani amandla injini. Kungenjalo, reading ungakwazi ukuba wattmeter isicelo. Kodwa lo izixhobo yokulinganisa lubiza kakhulu, ngenxa yesi sizathu, alikafiki kwandile. Kodwa multimeters sele abe yinxalenye yobomi bethu yonke imihla lusoloko kusetyenziswa. Kananjalo yokusebenza enkulu eyahlula nxamnye nezinye izixhobo, ezithi ezizodwa kakhulu.

isishwankathelo

Eli nqaku inceda ukuphendula umbuzo yokufumana indlela amandla physics kanye ikharakhtha eyahlulayo. Xa sele kusetyenzwa ke, xa bombane Oku kube lula ukubona. Kodwa ukuba ufuna ngokusebenzisa iindlela zobugcisa zale mihla bebenoyilungisa nawuphi na umsebenzi, nangaluphi na isigaba.
