Indlela Yokuhlukanisa Intambo Emibi Nenhle (Umhlahlandlela Wezindlela Ezi-2)
Okuqukethwe
Empilweni yangempela, akuzona zonke izintambo ezimakwe/ezinemibala njengezibomvu (izintambo eziqondile) noma ezimnyama (izintambo ezingezinhle). Ngakho-ke, udinga ukwazi ezinye izindlela zokunquma i-polarity yezintambo.
Ngingakwazi ukusebenzisa izintambo ezimbili zombala ofanayo nophozithivu kanye negethivu? Yebo kungenzeka. Amanye amafemu noma abantu bangakhetha ukusebenzisa izintambo ezinombala ofanayo ekuxhumekeni okuhle nokubi. Esimweni esinjalo, kuyoba nzima ukuhlukanisa izintambo komunye nomunye.
Ngasebenzisa izintambo eziningi zemibala ehlukene futhi ngezinye izikhathi ngisho nombala ofanayo wezintambo ezinhle nezingezinhle. Lokhu ngikwenza ngoba ngiyakwazi ukubehlukanisa ngaphandle kokuhilizisana, ngokwesipiliyoni sami seminyaka ngogesi.
Kulo mhlahlandlela, ngizokukhombisa ukuthi ungabona kanjani izintambo ezinhle nezimbi zanoma yiluphi uhlobo lokuxhuma.
Ngokujwayelekile izintambo eziphozithivu zimakwa zibomvu bese kuthi izintambo ezingezinhle zibe mnyama. Nokho, izintambo ezinezimbambo, izintambo ezisiliva, noma izintambo ezinombala obomvu nazo zingasetshenziselwa izintambo ezingezinhle. Endaweni yokukhanyisa, ucingo olumnyama luphozithivu, kanti ucingo olumhlophe lunegethivu. Izintambo zethusi zingama-pluses kusipika. Sicela uqaphele ukuthi amapulaki kagesi anezingxenye ezishisayo nezingathathi hlangothi - lezi yizinhlangothi eziphozithivu nezingezinhle, hhayi izintambo zangempela. Kwesinye isikhathi izintambo eziphozithivu nezinegethivu zibhalwe ukuthi "+" noma "-" futhi ungazikhomba kalula.
Indlela 1: Indlela yokubona ucingo oluhle noma olubi ezimweni ezivamile
Ake sifunde ukuthi ungazihlonza kanjani izintambo ezithwala i-voltage zisuka phansi - ngikhuluma ngezintambo ezingezinhle ezimweni ezifanayo. Ungazithinti izintambo ezingenalutho ngezandla. Zihlomise ngomhloli osebenzayo - abanye abahloli bayakhohlisa, ngakho qiniseka ukuthi uyabahlolela izintambo ezishayayo.
Amapulagi ezinto zikagesi zasendlini
Amapulaki kagesi awanazo izintambo noma izinhlangothi eziphozithivu nezingezinhle. Amapulagi anezigaba ezishisayo nezimaphakathi esikhundleni sezintambo noma izinhlangothi eziphozithivu nezingezinhle.
Izintambo zokunweba nethusi
Bheka izintambo ezinazimbambo entanjeni yokwandisa - ngokuvamile azinayo. Uma izintambo zakho ziyimibala efanayo, ngokuvamile ithusi, ucingo olunegethivu luwukuthungwa kwezimbambo. Landelela ubude bentambo ngezandla zakho ukuze uzwe izindawo ezigoqekile ezizoba intambo enegethivu.
Ukukhanya okukhanyayo
Ukuze unqume uhlobo lwezintambo endaweni yokukhanyisa, khumbula ukuthi kuzoba nezintambo ezintathu - ezinhle, ezimbi kanye nomhlabathi. Ucingo olumnyama luphozithivu, ucingo olumhlophe lunegethivu, kanti ucingo oluluhlaza lugayiwe. Ngakho-ke uma ufuna ukulenga i-chandelier, qaphela lolu hlelo lwezintambo, kodwa qhubeka ngokuqapha. Ungacisha amaswishi noma iswishi eyinhloko. (1)
Nokho, izintambo zethusi zingasetshenziselwa ukubeka phansi.
Izintambo zesipikha kanye ne-amplifier
Ngokuvamile izintambo zethusi ziba zinhle ezintanjeni zesipika noma ze-amplifier. Izintambo ezingezinhle ziyimicu esiliva.
Hlola Imanuwali Yomnikazi wakho
Ungasebenzisa imanuwali yakho ukucacisa uhlobo lwezintambo zakho. Izinhlobo ezahlukene zezimoto zinezintambo ezihlukene zokubhala ikhodi, ngakho qiniseka ukuthi uthenga imanuwali efanele.
Indlela yesi-2: Sebenzisa i-multimeter ukukhomba intambo ephozithivu nenegethivu
Sebenzisa i-multimeter yedijithali ukuze uhlole i-polarity yezintambo, ama-multimeters e-analog awonakaliswa kalula uma i-probe ixhunywe ngokungalungile.
Setha i-multimeter ku-voltage yamanje - vula inkinobho yokukhetha ukuze ukhombe ingxenye eno-"V" eduze kwayo. Xhuma intambo emnyama embobeni ebhalwe ukuthi COM, bese uxhuma intambo ebomvu embobeni ebhalwe ukuthi "V". Ekugcineni, xhuma ama-probes ndawonye ukuze ulungise i-multimeter, kufanele i-beep (i-multimeter) uma isebenza. Ukuze uhlole i-polarity yezintambo, yenza lokhu okulandelayo:
- Xhuma umthofu owodwa we-probe ocingweni olulodwa bese omunye uphenye ngakolunye uhlangothi lolunye ucingo. Ungasebenzisa iziqeshana zengwenya ezintanjeni.
- Hlola ukufundwa kwe-multimeter. Uma inani liphozithivu, intambo exhunywe ocingweni olubomvu lwenzwa iphozithivu. Uzothola ukufundwa okungaba ngu-9.2V. Kulokhu, intambo exhunywe ocingweni olumnyama inegethivu.
- Uma ukufunda kunegethivu, izintambo zakho ziyahlehliswa - intambo ocingweni olubomvu inegethivu futhi intambo ocingweni olumnyama iphozithivu, shintshanisa imikhondo ye-probe. (2)
- Uma inani le-voltage elingalungile liqhubeka, khona-ke i-multimeter yakho inephutha. Ishintshe.
Bheka ezinye zezihloko zethu ngezansi.
- Indlela yokunquma intambo engathathi hlangothi nge-multimeter
- Kusho ukuthini i-voltage engalungile ku-multimeter
- Ungahlola kanjani ucingo oluphansi lwemoto nge-multimeter
