Indlela hlola unit kahle amandla ekhaya

Ngokuhamba kwesikhathi, kodwa konke ezimpilweni zethu ngosuku olulodwa siphele, futhi kungenzeka lilimele lutho. Futhi ngokuphelele ngokuzumayo. Ngakho-ke akumangalisi ukuthi umuntu (noma cha) ngosuku thina eyakhiwe ukuqala ikhompyutha, ngokungazelelwe uzwa umsindo ajwayelekile we cooler egijima. ukuzwa engavamile kakhulu futhi singathandeki. Iyini inkinga? Uma ucabanga ngokucophelela, indlela deductive kungashiwo Baphetha ngokuthi uma lezi izinto zikagesi ingavuli, okusho ukuthi awekho amandla ihlinzekwa kuso. Kunengqondo? Noma okufana ezifana: akukho lunikezwe amandla supply, kungaba nge block efanayo wamanje akuyona nje ungena ohlelweni. Okufanele ukwenze nokuthi ungahlanganyela kanjani? Kanjani ukuhlola ugesi ukusebenza?

Kuyaqondakala ukuthi iyunithi yalezi wemfanelo wokuqinisekisa ukuthi ugesi kukhompyutha. Uma kushaywa noma ngenye okuyiphutha, ungalindela ukwehluleka nezinye izakhi sangaphakathi "ukugxusha." Ngakho-ke, wemfanelo omkhulu kuyadingeka ukuze asondele kukhethwa "izakhi" isici onokwethenjelwa futhi eqinile. Kanjani ukuhlola amandla uhlelo Iyunithi enikeza wedwa? Usebenzisa izindlela eziningana. Nangu omunye wabo, wenze udinga lokhu okulandelayo: bazama ukuvimba uchungechunge uxhumano kunethiwekhi, uma usebenzisa ezivamile incandescent ama-40 Watts. Ngakho-ke kuyokwenziwa kuyehla kube sezingeni eliphansi amathuba ukuthi kuyoba nesifunda esincane, kuleso simo isibani ngeke kukhanye e kukhanya egcwele.

Kanjani ukuhlola amandla PC sika supply kungenjalo? Indlela esilandelayo ukusebenzisa voltmeter. Kuze kube yimanje udinga ukufaka block enethiwekhi ekukaleni voltage ngesikhathi 9th umbadlana isokhethi contact. Ochwepheshe bakubiza ngokuthi "amandla eceleni". Kahle kahle, voltage kufanele kube cishe 5 volts. Uma ihambisana le ipharamitha, kusho ukuthi akukho ukumesaba futhi ngesibindi ukuxhuma iyunithi.

Kodwa lokhu kuhlole ayikahlanganiswa inqanyulwe. Kubalulekile ukwazi ukuthi ukuhlola amandla uhlelo Iyunithi enikeza ngesikhathi umthwalo walo. Ngenxa yale njongo, ungakwazi iphendukele ukusetshenziswa okuthiwa resistors silingo-up. Bavumela ukuchaza iyunithi nokwethenjelwa nge okungenzeka sezingeni eliphezulu. Ochwepheshe Kunconywa ukuba ukhethe resistors kabani Amandla 20-25 Watts. Ziyakwazi ekahle ukuze uhlole amabhlogo onobuhle eziningi phakathi intengo isigaba.

Ngakho indlela ukuhlola ikhompyutha amandla Iyunithi enikeza usebenzisa wokudonsa up resistors? Badinga ukuxhuma kwi iyunithi bese ukukala umthwalo, njalo ukunaka imithetho avumelekile futhi wabonisa kucecevu idatha ye lisebenze. Uma imiphumela olitholile, ahambisane, kusho ukuthi iyunithi singamethemba ngokuphelele. Nokho, uma le mifanekiso angaphezu kwalawo aboniswe kucecevu idatha, kusho ukuthi iyunithi kungaba alithembekile nje kuphela kodwa futhi kuyingozi ukusebenzisa.

Manje ngoba sewuyazi ukuthi kanjani ukuhlola amandla uhlelo Iyunithi enikeza. Kukhona enye indlela okungakusiza kulesi simo. Nqamula zonke amandla kusuka ekhadini ihluzo, umbadlana, hard drive, njll (Ungakwazi ukushiya drive DVD, akusiyo wamesaba kakhulu voltage kwemali). Ngaphezu kwalokho kubalulekile ukuthatha Plume amandla esikhulu ukuze isekhethi umbadlana kanye nezixhumanisi yayo omnyama oluhlaza Usebenzisa abavamile iphepha isiqeshana (zenzeka). Thatha umhloli. Okuphakela amandla ukuxhuma kunethiwekhi kuqala, bese uvule ngumuntu inkinobho. Uma uqala, the black ukuhlolwa ukuhola umhloli okuzofakwa kunoma yiziphi izintambo ugesi omnyama abomvu yanjalo ezifakiwe nezinye, izikhonkwane ezinemibala. Manje nemingcele evelayo esibukweni lakho lokuhlola, ebhekisela izibalo ezilandelayo (lezi zibalo udinga ukubona):

- orange - 3.3 V;

- white - 5V;

- abomvu - 5V;

- ophuzi - 12b;

- pink (noma onsomi) - 5V;

- blue - 12V.

Uma amarekhodi akho okungenani kuphambuka lezi izinkambiso, kusho ukuthi iyunithi inikeza voltage noma eliphezulu kakhulu noma eliphansi, futhi ngenxa yalokho, ayilungile.
