Watts, volts kunye amps

IiWatts

Ngokuqinisekileyo "uyagula" ngokuthi "Ndithenge i-25-watt light bulb" kodwa awazi ncam ukuba yintoni i-watt. I-Watt iyunithi yemilinganiselo esetyenziswa kwimilinganiselo ye amandla ombane kwaye leyo yinxalenye yeNkqubo yeHlabathi. NgesiNgesi inegama elithi watt. Ilingana nejoule enye ngomzuzwana. Isimboli yayo ngu-W kwaye inika imbeko kwingcali yezibalo yase-Bhritane kunye neinjineli uJames Watt.

Kule nqaku siza kuphengulula iiwati, ingaba ibaluleke kangakanani ebomini bethu kwaye siza kuyithelekisa nee-volts, into ekulula kakhulu ukudida ngayo namhlanje. Ngaba uyafuna ukufunda konke ngayo? Qhubeka ufunda.

 Ukusetyenziswa kweWatts

Amandla ombane

Enye yeendawo apho le yunithi yokulinganisa isetyenziswe khona intsimi yombane. Kuqhelekile ukuyibona ukuphawula amandla ombane ukuba isixhobo sinakho kwaye sinokubonakaliswa kwii-watts. Amandla anamandla ngakumbi, iiyunithi eziphakamileyo zomlinganiso ezinjenge kilowatt okanye megawatt zisetyenzisiwe. Benza nje ukubala kunye nokubala kube lula.

Ukutsho amandla ombane a Ipaki ye-eolico kwakuthethwa ngeegawathi, umzekelo. Kwelinye icala, ukwazi amandla ombane angene kwikhaya, sithetha ngeekilowatts. Kwaye amandla ombane abhekisa kwinqanaba apho amandla aveliswa khona okanye asetyenziswayo xa kusenziwa umsebenzi. Ukuqonda okungcono: ukuba sine-80 watt light bulb kwiyure enye, i-80 watt / iyure iya kube isetyenzisiwe.

I-watt / iyure ibonakala kumandla ngeyunithi yexesha. Oko kukuthi, inani lamandla elenzelwe ukugcina amandla ebhalbhu ekhanyise ixesha elithile. Njengoko bekutshiwo ngaphambili, i-watt enye ilingana noJulayi ngomzuzwana. Ke ngoko, eso sixhobo sisebenzisa i-watt yamandla ombane sisebenzisa i-joule enye ngomzuzwana. Ukuba i-bulb ye-watt engama-80 ihlala ihleli iyure enye, i-joule efanayo iya kuba ngama-288.000 ngelo xesha.

Ama-watts angama-80 ngeyure = ama-joule angama-80 ngomzuzwana x 3600 (kwiyure nganye kukho imizuzu engamashumi amathandathu; kwimizuzu yonke, kwimizuzwana engamashumi amathandathu. Ngoko ke: 60 x 60 = 3600)

Iiyure ezingama-80 = iiyure ezingama-288.000

Amandla ombane koomatshini

Iinjini zomoya

Koomatshini, iimoto kunye nezixhobo zamandla iiyunithi zomlinganiselo ziikhilowatts okanye iimegawatts. Ezi yunithi zinamandla okulinganisa ihashe kunye namandla alinganayo, umzekelo.

Kufuneka ichazwe ukuba kwiimeko ezininzi ukudideka kuyenziwa malunga ne-watt. Oku kwenzeka kuba umntu ngamnye ukhetha ukukhetha iyunithi yokulinganisa asebenzise ngayo ukusebenza. IiMegawatts zisetyenziselwa ukuvelisa amandla ahlaziyekayo. Iyunithi yokulinganisa ukukhankanya amandla ombane aveliswa kwifama yelanga okanye yomoya. Namhlanje Amandla ahlaziyekayo Bavelisa isixa esikhulu samandla kumazwe amaninzi anceda ukusombulula iingxaki zongcoliseko kunye notshintsho lwemozulu.

Ukudideka okukhulu

Watt kunye volt

Iivolthi

Xa abantu bedidekile neeyunithi zomlinganiselo wamandla ombane, bahlala bephutha ii-watts zeevolts. Sesona siphithiphithi siqhelekileyo sikhoyo, kuba omabini la magama asetyenziswa kwicandelo lombane kunye nelombane kunye nesandi esifanayo.

Ukuthintela le mpazamo, kufuneka siqale kwiingcaciso. Sitshilo ukuba i-watt yiyunithi yokulinganisa kwamandla ombane. Nangona kunjalo, volt ibhekisa kumandla ombane okanye amandla ombane anokubakho ikhona. Oko kukuthi, umahluko kumandla ombane akhoyo phakathi kweendawo ezimbini ezithile. Ukucaca, enye ibhekisa kwixesha levolthi kwaye elinye kwigunya lamandla.

Unokuva ngokulula abantu abaninzi besithi "zingaphi iivolthi ezisebenzisa esi sixhobo." Kufuneka kuqatshelwe ukuba I-volt ASIYunithi yomlinganiselo wamandlakodwa ukusuka kwimpixano.

Iiyure ze-Kilowatt kunye ne-kilowatt

Ibhili yombane kunye nokubaluleka kokwazi iewatts kunye neevolts

Olunye udideko oluhlala lukhona kukubhidanisa ii-watts kunye neeyure zeeyure. Kwaye yile xa sithetha ngayo iikhilowathi sithetha iyunithi yamandla. Ukuyiqonda ngcono, siyithelekisa namandla enjini yeinjini yemoto. Kuqhelekile ukuva izimvo ezinje "Ndisebenzise i-kilowatts ezingama-200 zokukhanya". Oku akunangqondo, kuba kuyabhidaniswa neeyure zekhilokathi. Ngokuqinisekileyo awuvanga kusithiwa "imoto yam eluhambeni idle amahashe angama-60". Amandla ehashe ngamandla esithuthi, hayi ukusetyenziswa kwamandla.

Ukucaca ngokupheleleyo, kuya kufuneka ucinge ukuba i-watt lixesha elikhawulezileyo. Nanini na xa sithetha ngeewatts, kufuneka zibekho ngexesha elithile. Oku akunjalo, umzekelo, kwimeko yeradiyetha yombane etya rhoqo.

IiWatts zikwasetyenziswa kwilizwe lezemidlalo, ngakumbi kwicandelo lokuhamba ngebhayisikile. Apha isetyenziselwa ukubhekisa kumlinganiso wamandla oza kurekhoda amandla ebalekiswa yimbaleki ukuze abe nakho ukuhambahamba ngebhayisikile yakhe. Ukuze ukwazi la mandla akhankanywe apha ngasentla, kuqhelekile ukuba isithuthi esinamavili amabini sibeke izixhobo zombane kwindawo yothumelo ngokukodwa.

Watt kunye neeps

Umahluko phakathi kweewatts volts kunye neeamps

Xa sifuna ukwazi ukuba sisebenzisa kangakanani isixhobo sombane, kuqhelekile ukudida ii-watts nee-Amps. Nangona amanye amaxabiso anokufana (kwimeko yee-incandescent bulbs) azinanto yakwenza nomnye nomnye. Ngale ndlela, amandla kwii-watts yeyona nto inokwenzeka ukuba isixhobo siyisebenzisa (kuya kufuneka ithathelwe ingqalelo ukukhetha amandla ekontraki kunye nokukhusela i-ICP ekusebenzeni). Kwelinye icala, Ii-Amps zisibonisa «amandla abonakalayo» kwaye isetyenziselwa ukulinganisa ngokuchanekileyo iintambo ukuze singazivelisi isiphaluka esifutshane.

La magama onke abonakalisiwe kumthetho osayilwayo wombane kwaye kungenxa yokuba iikhilowathi zekhontrakthi zamandla zididekile ngokulula kunye ne-kWh yamandla esiwasebenzisayo. Eyokuqala banexabiso elimiselweyo, ngelixa imizuzwana iyahluka ngokuxhomekeka kwindlela oyisebenzisa ngayo.

Into ebalulekileyo malunga nesi sithuba sipheleleyo kukwazi ukwahlula iikhonsepthi ukuze, xa uhlawula ityala lethu lombane, sazi kakuhle ukuba sihlawulela ntoni.
