Ihlala ixesha elingakanani imitha yombane?

Shicilela. Ibhetri iyaokokugqibelamalunga neeyure ezingama-200 kwinqanaba elinyeImitha yamandlakwaye malunga neeyure ezili-150 kumanqanaba amabini macala e-LRimitha. Inqanaba ngalinyeamandlaInzwa ithatha ibhetri enye yeselfowuni CR2032.

Hee bafo, uPaul apha uTheEngineeringMindset.com. Kule nqaku siza kujonga ukuba yeyiphi i-kilowatt yeyure.

Siza kugubungela iiyure ze-kilowatt, i-watts, i-kilowatts kunye ne-joules, ukuguqula phakathi kwe-watts kunye ne-kilowatts, kunye nendlela yokubala ukusetyenziswa kweeyure zakho ze-kilowatt kunye neminye imizekelo eyenziwe ekugqibeleni. Kwaye okokugqibela, uyibala njani imali oyibhatalayo yenyanga. Okwangoku sele uqaphele ukuba amatyala akho eluncedo abonisa ukuba uhlawulisiwe ngesixa se-kWh esisisebenzisayo, kwaye xa uthenga umbane axabiswa kwii-Ws okanye ii-kWs.

Ityala lakho lombane linikwa kwi-kWh, oko kuthetha ukuba iiyure zekhilokathi. Yiloo nto ubungakanani bombane obufunwayo ngaphezulu kwexesha elithile. Amandla aphindaphindwe ngexesha ngamandla, ke masikhawuleze sijonge ukuba yintoni i-kilowatt kwaye emva koko sibuyele kwii-kilowatt-iiyure kunye nokubala, kwaye loo nto yenza izinto zibe lula kakhulu.

Kwimpahla yombane oyithengayo, uya kubona ixabiso kwi-W okanye kW, okt H. kwii-watts okanye kwi-kilowatts.

Le yimfuno yamandla yento leyo, itel isixelela ukuba angakanani amandla ngomzuzwana ekuthatheni umsebenzi. Uyabona ukuba le heater yomoya inemveliso yeekilowatts ezimbini kwaye ibhalbhu yokukhanyisa ine-100 watts. I-Kilo ithetha i-1000 kunye ne-watt ngamandla athiywe ngegama lenjineli egama linguJames Watt.

Ukuchaneka, i-watt enye ithetha i-joule enye ngomzuzwana, kwaye iyure enye ye-kilowatt yi-3.6 megajoules. Yintoni ijoule? Ijoule sisixa samandla esigqithiselwe ukwenza umsebenzi.

Ukutya kwethu kunamandla kwiijoules okanye iikhalori okanye, kwaye sisebenzisa oku ukufudumeza namandla emizimba yethu. Kodwa kule meko i-joule ngokwamandla ombane sisixa samandla asinikiweyo njengobushushu xa umbane wombane we-ampere ugeleza ngokuchasene ne-ohm enye okomzuzwana-iziseko zombane emva koko ungazibandakanya nabanye babukele amanqaku zisebenza njani umbane. Ikhonkco ngoku liphezulu ekunene kwesikrini okanye ungabona inkcazo yendawo ezantsi.

Ungaguqula ii-kilowatts zibe zii-watts ngokuphindaphinda nje nge-1,000 i-kilowatt ephindaphindwe nge-1,000 yi-1,000 watts. Unokuguqula ii-watts zibe yi-kilowatts ngokwahlulahlula i-1,000, ke ii-watts ezili-100 ezahlulwe nge-1,000 zii-0.1 kilowatts.

Ukuze sikwazi ukubala ukuba isifudumezi sisebenzisa umbane ongakanani na kufuneka sazi ukuba siwufuna kangakanani na umbane kwaye siya kuba sisekude kangakanani, siyabona ukuba le nto ikalwe ngee-kilowatts ezimbini, ukuba awunawo umlinganiselo into onokuyithenga enye yezi iplagi zamandla zokujonga amandla eziza kukubonisa iivolts, ii-amps, ii-watts kunye neeyure ze-kilowatt. Zibiza ixabiso eliphantsi kwaye kulula kakhulu ukuzisebenzisa, ke ndizakushiya ikhonkco kule nkcazo ingezantsi. Ukuba ufuna enye yezi, jonga ngaphandle.

Ngoku buyela kwisifudumezi. Ke sifuna ukwazi ukuba zingaphi iiyure zeekilowatt ezizityayo. Siyazi ukuba singasebenzisa ifomula yamandla elingana namandla aphindaphindwe ngexesha ziiyure ezintathu.

Ke iikhilowathi ezimbini eziphindaphindwe ngeeyure ezintathu zilingana neeyure ezintandathu zekhilokathi. Kodwa kuthekani ukuba isifudumezi sihamba kuphela imizuzwana engama-30? Sisengayisebenzisa ifomula yamandla, kodwa kuba sihlawuliswa ngeeyure zeekhilokathi, kufuneka siguqule imizuzwana ibe yeyure. Ke yimizuzu engama-60 kunye neyure kunye nemizuzwana engama-60 ngomzuzu.

Ama-60 aphindwe ngama-60 asinika imizuzwana engama-3 600 ngeyure. Singaliguqula ixesha lokubaleka lesibini libe yiyure ngokwahlulahlula imizuzwana engama-30 ngo-3,600. Oko kuthetha ukuba sibaleka iiyure ezingama-0.0083.

Ke ii-kilowatts ezimbini eziphindaphindwe ngeeyure eziyi-0.0083 zilingana ne-0.0167 kilowatt iiyure.

Njani ngezinto ezincinci xa zikhona? Kulinganiselwe iwatts? Sicinga ukuba sine-60 watt lightbulb kwaye isebenza iiyure ezili-10, sisasebenzisa ifomula yamandla alingana namandla aphindwe ngexesha, kodwa kufuneka siguqule ii-watts kwii-kilowatts njengoko sihlawuliswa ngeeyure ze-kilowatt .60 yahlulwe nge-1,000 ngu-0.06. iikhilowathi, kunye ne-0.06 kilowatts eziphindaphindwe ngexesha lokusebenza kweeyure ezili-10 zinika iiyure ezi-0.6 zeekhilowathi.

Ukuba sifuna ukubala iindleko, simane siphindaphinda ukusetyenziswa kweeyure zeekhilowathi ngumrhumo wombane womboneleli wethu wombane ngeyure nganye yekilowatt. Ukuba sijonga isifudumezi-fan, esinee-kilowatts ezimbini, kwaye masiyiqhube iiyure ezintathu, emva koko ii-kilowatts ezimbini eziphindwe kathathu iiyure zilingana neeyure ezingama-kilowatt ezintandathu. Inkampani yethu yombane isithengisela umbane ngeesenti ezili-10 ngeyure nganye yekilowathi, okt iiyure ezintandathu zekhilowathi ziphindaphindwe nge-0,1 zeedola nge-kilowatt ngeyure, elingana nama-60 eesenti

Njani ngokubala usetyenziso lombane lwenyanga? Ewe, kufuneka senze itafile yazo zonke izixhobo zombane esakhiweni, emva koko sibhale ukusebenza kwazo. Khumbula ukubala ubungakanani bento nganye onayo kwaye uqiniseke ukuba into nganye ikwi kilowatts. Emva koko kufuneka sibala ukuba zingaphi iiyure ngenyanga abakuzo.

Ukusuka apho sinokubala ukusetyenziswa kwamandla kwento nganye ngokuphindaphinda amandla alingana namandla kwifomula yexesha. Ukuba wenze oku kuzo zonke izinto, yongeza nje amaxabiso kwikholamu yezaMandla kwaye ufumana ukusetyenziswa ngokupheleleyo ngeeyure zekhilokitha ngenyanga. Nje ukuba uyazi oku, unokubala iindleko.

Sukukhohlisa Kuya kubakho ezinye iindleko kwi-invoyisi yomthengisi, izinto ezinje ngerhafu, njl. Ke uyazi ukuba uyayifuna na phaya, emva koko ungayifaka ngokwahlukeneyo ngokweemfuno zakho. Ok ibiyilelo inqaku, ndiyathemba ukuba uyonwabele kwaye wakunceda.
