Iyiphi intambo eshisayo uma izintambo zombili zinombala ofanayo?

Ukusebenza ngezintambo ezibukhoma kuwumsebenzi obucayi futhi oyingozi, futhi noma yisiphi isisebenzi sikagesi sizokutshela ukuthi kubaluleke kangakanani ukwazi ukutshela izintambo ezibukhoma ezintanjeni ezingathathi hlangothi. Awufuni ukuwaxuba noma kungaholela kuzo zonke izinhlobo zezinkinga, okuvame kakhulu ukujikeleza okufushane. Nakuba izintambo ngokuvamile zinekhodi yombala ukuze zibonakale kalula, ngezinye izikhathi azikhonjwa. Lokhu kungase kube ngenxa yezinqumo ezingezinhle zokufaka izintambo ekhaya lakho noma idivayisi lapho umenzi ekhethe khona umbala ofanayo wezintambo.

Kungakhathaliseki ukuthi yisiphi isizathu, udinga ukwazi ukuthi iziphi izindlela ongazisebenzisa ukuze ubone ucingo olushisayo lapho izintambo zombili ezisebenzayo nezingathathi hlangothi zinombala ofanayo. Kulesi sihloko, sizokufundisa ngqo ukuthi ungakwenza kanjani lokhu, ngakho qhubeka ufunda.

Lapho usebenzisana nezintambo zikagesi zombala ofanayo, indlela engcono kakhulu yokunquma ukuthi yikuphi okushisayo nokungathathi hlangothi ukusebenzisa i-multimeter enhle. Ixhume ocingweni ngokulandela imiyalelo yomkhiqizi futhi ucingo olune-voltage kuyo kuzoba intambo eshisayo.

Ukuqonda umehluko phakathi kwezintambo ezishisayo nezintambo ezingathathi hlangothi

Ukuhlaziywa kwamagama okulula kuzokutshela ukuthi ucingo olushisayo lusebenza endaweni ephakeme kunezinga lokushisa elivamile. Uma zingasebenzi, zonke izintambo ziyizintambo ezibandayo uze uhambise ugesi kuzo. Ukuhambisa ugesi kukhiqiza ukushisa, futhi ucingo oluthwala ugesi luyashisa. Yingakho intambo ephilayo ibizwa nangokuthi intambo eshisayo. (1)

Kusistimu yesigaba esisodwa esijwayelekile, uzoba nezintambo ezimbili ezigijima ohlelweni, olulodwa lwazo oluphethe ugesi. Lena intambo ezoxhuma iswishi yakho kumadivayisi afana nelambu lokukhanyisa, ifeni, noma ezinye izinto zikagesi. Kunezimo ezimbili ovame ukuzibona uma usebenza ngezintambo ezinemibala. Kungaba izintambo ezibomvu nezimnyama noma ezimnyama nezimhlophe. Esimweni sokuqala, ucingo olushisayo ngokuvamile lubomvu, kanti, esimeni sesibili kuvamise ukuba yintambo emnyama eshisayo kanti ucingo olumhlophe luyintambo engathathi hlangothi.

Kodwa-ke, uma zombili zinombala ofanayo wezintambo, ungase ukuthole kudida kakhulu ukunquma ukuthi iyiphi intambo kagesi eshisayo nokuthi iyiphi engokwemvelo. Ngenhlanhla, kunezindlela ongazisebenzisa ukuze uhlonze kahle izintambo ukuze ungazixhumi ezitolo nasezimpahleni zikagesi ngokungalungile.

Ukuthola ukuthi iyiphi intambo eshisayo uma yomibili inombala ofanayo

Ungahlola ukuthi intambo kagesi ibukhoma noma ingathathi hlangothi usebenzisa izindlela ezimbalwa ezihlukene. Nokho, izindlela eziningi ezitholakalayo zineziqondiso ezithile zokuphepha. Lokhu kusho ukuthi umuntu othanda ukuzilibazisa akufanele awasebenzise njengoba kungase kubangele isifunda esifushane noma, esimweni esibi kakhulu, ukufa komuntu oxhumana nezintambo, njengoba i-voltage ephezulu iyabulala.

Ngakho-ke, sizochaza kabanzi ngenqubo okuwukuphela kwayo ephephile ukuyisebenzisa futhi eyamukelwa kabanzi yimvelo yayo.

Indlela esikhuluma ngayo ukusebenzisa i-multimeter. Ukwazi ukuthi isetshenziswa kanjani kungaba wusizo kakhulu ezimeni ezahlukahlukene. Kulokhu, angakwazi ukunquma kalula ukuthi yikuphi ngokuhambisa ugesi odlula izinzwa zakhe.

Qinisekisa ukuthi uyazi ukuthi i-multimeter isebenza kanjani ngaphambi kokuthi unqume ukuyisebenzisela ukuhlola izintambo ezishisayo nezemvelo.

Manje njengoba usune-multimeter esebenzayo, uzodinga ukulandela lezi zinyathelo ukuze unqume intambo eshisayo nentambo engathathi hlangothi.

1. Setha i-multimeter ibe yimodi ye-voltage ye-AC, evame ukubizwa ngokuthi i-HVAC, i-VAC, noma i-200V. Lokhu kungase kwehluke kuye ngezwe okulo kanye nohlobo olusebenzisayo. Qiniseka ukuthi uthenga imitha yedijithali yekhwalithi enhle ukuze ungayifinyezi ngephutha bese uylimaza.
2. Thinta i-probe ebomvu ku-multimeter uye kwenye yezintambo, bese uthinta i-probe emnyama emzimbeni wesokhethi, ovame ukwenziwa ngensimbi. Icala lizosebenza njengesiteshi sokumisa phansi, okusho ukuthi uma usuxhume ocingweni oluphilayo, umsinga uzogelezela phansi futhi ngeke udale umonakalo ku-multimeter noma kuwe.
3. Bheka ukufundwa okuvezwa manje ku-multimeter yakho. Uma ubona ukufundwa okungu-0 noma eduze kakhulu nakho, ucingo oluthintayo ngophenyi olubomvu aluthathi hlangothi ngombala. Kodwa-ke, uma ukufundwa ku-multimeter yakho kuzungeze i-100-120 volts, khona-ke uthinta ucingo oluphilayo ngezandla zakho. Leli nani lingase futhi libe phakathi kuka-200 no-240 kuye ngokulawulwa kwamandla kagesi ezweni lakini. (2)
4. Phinda uhlole izintambo ukuze uqiniseke ukuthi iyiphi, bese umaka intambo ebukhoma ngokunamathisela ucezu oluncane lwetheyiphu kagesi kuyo. Ungasebenzisa futhi ezinye izindlela, kodwa qiniseka ukuthi azikho ezilimaza ucingo.

Ukufingqa

Ugesi uyinto eyingozi, futhi awulitholi ithuba lesibili lokulungisa amaphutha akho uma umosha okuthile. Yingakho kubaluleke kakhulu ukwazi ukuthi yiziphi izintambo ezibukhoma futhi yiziphi ezingathathi hlangothi. Ukuxhumeka okungalungile kungaholela kuzo zonke izinhlobo zezinkinga ongafuni ukuzibona. Sicela ulandele umhlahlandlela wethu ngokucophelela futhi uqiniseke ukuthi ulandela zonke izincomo zokuphepha.

Bheka ezinye zezihloko zethu ngezansi.
