Momwe Mungasiyanitsire Waya Woipa ndi Wabwino (2 Njira Zowongolera)
Zamkatimu
M'moyo weniweni, si mawaya onse omwe amalembedwa / amitundu yofiira (mawaya abwino) kapena akuda (mawaya oyipa). Choncho, muyenera kudziwa njira zina kudziwa polarity mawaya.
Kodi ndingagwiritse ntchito mawaya awiri amtundu umodzi ngati zabwino ndi zoipa? Inde ndizotheka. Makampani ena kapena anthu angasankhe kugwiritsa ntchito mawaya amtundu womwewo kuti alumikizane ndi zabwino ndi zoyipa. Zikatero, zidzakhala zovuta kusiyanitsa mawaya kwa wina ndi mzake.
Ndinagwiritsa ntchito mawaya angapo amitundu yosiyanasiyana ndipo nthawi zina ngakhale mtundu womwewo wa mawaya abwino ndi oyipa. Ndimachita izi chifukwa ndimatha kuwasiyanitsa popanda kukangana, kutengera zaka zomwe ndakumana nazo ndi magetsi.
Mu bukhuli, ndikuwonetsani momwe mungadziwire mawaya abwino ndi oipa amtundu uliwonse wa kugwirizana.
Nthawi zambiri mawaya abwino amakhala ofiira ndipo mawaya oyipa amakhala akuda. Komabe, mawaya okhala ndi nthiti, mawaya asiliva, kapena ngakhale mawaya amitundu yofiira angagwiritsidwenso ntchito pa mawaya olakwika. Pazowunikira, waya wakuda ndi wabwino, ndipo waya woyera ndi woipa. Mawaya amkuwa ndi ma pluses pa speaker. Chonde dziwani kuti mapulagi amagetsi ali ndi magawo otentha komanso osalowerera - awa ndi mbali zabwino komanso zoyipa, osati mawaya enieni. Nthawi zina mawaya abwino ndi oyipa amalembedwa "+" kapena "-" ndipo mutha kuwazindikira mosavuta.
Njira 1: Momwe mungadziwire waya wabwino ndi woyipa pazofanana
Tiyeni tiphunzire momwe mungadziwire mawaya omwe amanyamula magetsi kuchokera pansi - ndikulankhula za mawaya oyipa omwe amafanana. Osagwira mawaya opanda kanthu ndi manja opanda kanthu. Dzikonzekereni ndi tester yogwira ntchito - oyesa ena ndi achinyengo, choncho onetsetsani kuti mwawayesa mawaya omwe ali ndi ndalama.
Mapulagi a zipangizo zapakhomo
Mapulagi amagetsi alibe mawaya abwino komanso oyipa kapena mbali. Mapulagi ali ndi magawo otentha komanso osalowerera m'malo mwa mawaya abwino ndi oyipa kapena mbali.
Zingwe zowonjezera ndi mkuwa
Yang'anani mawaya okhala ndi nthiti pa chingwe chowonjezera - nthawi zambiri amakhala opanda pake. Ngati mawaya anu ali ndi mitundu yofananira, nthawi zambiri amkuwa, waya woyipa ndi mawonekedwe a nthiti. Tsatirani utali wa waya ndi manja anu kuti mumve madera otsetsereka omwe adzakhala mawaya oyipa.
Kuwala kwa kuwala
Kuti mudziwe mtundu wa mawaya muzowunikira, kumbukirani kuti padzakhala mawaya atatu - zabwino, zoipa ndi nthaka. Waya wakuda ndi wabwino, waya woyera ndi woipa, ndipo waya wobiriwira ndi wopota. Kotero pamene mukufuna kupachika chandelier, tcherani khutu ku dongosolo la waya, koma pitirizani kusamala. Mutha kuzimitsa masiwichi kapena chosinthira chachikulu. (1)
Komabe, mawaya amkuwa angagwiritsidwe ntchito poyika pansi.
Mawaya a speaker ndi amplifier
Nthawi zambiri mawaya amkuwa amakhala abwino mu mawaya olankhula kapena amplifier. Mawaya opanda pake ndi ulusi wasiliva.
Yang'anani Buku la Mwini Wanu
Mukhoza kugwiritsa ntchito bukhu lanu kuti mudziwe mtundu wa mawaya anu. Magalimoto amtundu wosiyanasiyana ali ndi ma waya osiyanasiyana, choncho onetsetsani kuti mwagula buku lolondola.
Njira 2: Gwiritsani ntchito multimeter kuti muzindikire waya wabwino ndi woipa
Gwiritsani ntchito multimeter ya digito kuti muwone polarity ya mawaya, ma multimeter a analogi amawonongeka mosavuta ngati kafukufukuyo alumikizidwa molakwika.
Khazikitsani ma multimeter kukhala-voltage yapano - tembenuzirani batani losankhira kuti muloze gawo lomwe lili ndi "V" pafupi nayo. Lumikizani kutsogolo kwakuda ku doko lotchedwa COM, ndiyeno gwirizanitsani njira yofiira ku doko lolembedwa "V". Pomaliza, gwirizanitsani ma probes palimodzi kuti musinthe ma multimeter, iyenera kuyimba (multimeter) ngati ikugwira ntchito. Kuti muwone polarity ya mawaya, chitani izi:
- Lumikizani chingwe chimodzi cha kafukufuku ku waya wina kenako fufuzani mbali ina ya waya wina. Mukhoza kugwiritsa ntchito tatifupi alligator pa mawaya.
- Onani kuwerenga kwa ma multimeter. Ngati mtengo uli wabwino, waya wolumikizidwa ndi waya wofiira wa sensa ndi wabwino. Muwerenga pafupifupi 9.2V. Apa, waya wolumikizidwa ku waya wakuda ndi wopanda pake.
- Ngati kuwerenga kuli kolakwika, mawaya anu amatembenuzidwa - waya pawaya wofiyira ndi wolakwika ndipo waya pawaya wakuda ndi wabwino, sinthanani zowongolera. (2)
- Ngati mtengo wamagetsi olakwika ukupitilira, ndiye kuti ma multimeter anu ndi olakwika. Sinthani izo.
Onani zina mwazolemba zathu pansipa.
- Momwe mungadziwire waya wosalowerera ndi multimeter
- Kodi ma voltage negative amatanthauza chiyani pa multimeter
- Momwe mungayang'anire waya wapansi wagalimoto ndi multimeter
