Taƙaice:

A cikin da'irori, resistors wani abu ne mai mahimmanci wanda zai iya iyakance magudanar ruwa da canza wutar lantarki zuwa makamashin thermal. Lokacin da aka haɗa ƙarfin lantarki na 380V da 220V zuwa ƙarshen ƙarshen resistor, za a sami bambance-bambance masu mahimmanci. Wannan labarin zai bincika waɗannan bambance-bambance daga bangarori uku: bambancin wutar lantarki, asarar wutar lantarki, da aminci.

gabatarwa:

Tare da ci gaba da ci gaban fasaha da ci gaban al'umma cikin sauri, samar da wutar lantarki ya shahara a kowane lungu. Matsayin ƙarfin wutar lantarki kuma ya bambanta, tare da mafi yawan 380V da 220V. Menene bambanci a cikin aikin resistor a matsayin ainihin kayan lantarki a cikin da'ira a ƙarƙashin yanayin ƙarfin lantarki guda biyu?

1. Bambancin wutar lantarki:

Ƙarfin wutar lantarki yana nufin bambancin yuwuwar, wanda aka auna a volts (V). 380V da 220V bi da bi suna wakiltar matakin ƙarfin lantarki na wutar lantarki, wanda ke nufin cewa bambancin ƙarfin lantarki tsakanin ƙarshen biyu na resistor shima ya bambanta a cikin duka biyun. A bisa ka’idar Ohm, alakar da ke tsakanin wutar lantarki da halin yanzu ita ce U=IR, inda U ita ce voltage, I is current, R kuma ita ce juriya. Ana iya ganin cewa a karkashin irin wannan juriya, idan an haɗa shi da wutar lantarki na 380V, na yanzu zai fi girma fiye da lokacin da aka haɗa da wutar lantarki 220V, saboda bambancin wutar lantarki yana haifar da canji a halin yanzu. Don haka, lokacin da aka haɗa band ɗin juriya zuwa wutar lantarki tare da ƙarfin lantarki daban-daban a ƙarshen duka, za a sami bambance-bambance a girman halin yanzu.

2. Rashin wutar lantarki:

Ƙarfi shine ma'auni mai mahimmanci a cikin da'ira, wanda ke wakiltar ƙimar canjin makamashi a kowace raka'a na lokaci, wanda aka auna a watts (W). Bisa ga tsarin wutar lantarki P=IV, inda P yake wuta, I na yanzu, kuma V shine ƙarfin lantarki, ana iya ƙayyade cewa ikon yana da alaƙa da samfurin halin yanzu da ƙarfin lantarki. Don haka, lokacin da aka haɗa hanyoyin samar da wutar lantarki daban-daban a duka ƙarshen resistor, asarar wutar kuma zata bambanta. Lokacin da aka haɗa da wutar lantarki na 380V, saboda babban halin yanzu, asarar wutar lantarki kuma za ta karu daidai da haka; Lokacin da ake haɗawa da wutar lantarki na 220V, saboda ƙananan halin yanzu, asarar wutar yana da ƙananan ƙananan.

3. Tsaro:

Tsaro shine damuwa ta musamman lokacin amfani da da'irori. Lokacin da aka haɗa wutar lantarki ta 380V a duka ƙarshen resistor, cutarwa ga jikin ɗan adam yana ƙaruwa sosai saboda babban halin yanzu. Hatsarin girgiza wutar lantarki na iya haifar da munanan rauni ko ma yanayi masu barazana ga rayuwa. Sabili da haka, lokacin da ake haɗawa da wutar lantarki mai ƙarfin lantarki, dole ne a ɗauki matakan tsaro masu dacewa, kamar ƙirar da'ira mai ma'ana, kariyar kariya, da sauransu. .

Taƙaice:

A matsayin babban abin da ke cikin da'ira, masu adawa na iya samun wasu bambance-bambance lokacin da aka haɗa su zuwa tushen wutar lantarki 380V da 220V a ƙarshen duka. Lokacin haɗawa da wutar lantarki na 380V, halin yanzu yana da girma, asarar wutar lantarki yana da girma, kuma haɗarin aminci ya karu; Lokacin da aka haɗa da wutar lantarki na 220V, halin yanzu yana da ƙananan ƙananan, asarar wutar lantarki yana da ƙananan ƙananan, kuma aminci yana da girma. Don haka, lokacin zayyana da'irori, ya zama dole a zaɓi matakan ƙarfin lantarki daban-daban gwargwadon buƙatu na ainihi kuma ɗaukar matakan tsaro daidai lokacin amfani da gaske don tabbatar da aiki na yau da kullun na kewayawa da amincin mutum.

Lura: Wannan labarin don tunani ne kawai, kuma takamaiman yanayi yana buƙatar yin hukunci da kulawa bisa ainihin buƙatu da takamaiman ƙirar kewaye.
