Ukubaluleka kwesilinganiso samandla: ekwakhiweni kwesizungu se-elekthronikhi, into yokuqala okufanele uyicabangele lapho ukhetha isilinganiso saso samandla.Le nkomba ichazwa ekushiseni okujwayelekile okukhona kanye nomswakama, ambonise ukujikeleza komoya okuzungezile, futhi kukhombisa amandla aphezulu umphikisi angamelana ngaphansi komthwalo oqhubekayo wesikhathi eside ngaphandle kokulimaza noma ukuguqula kakhulu ukusebenza kwawo.Umthetho obalulekile wokusetshenziswa okuphephile ukuthi ukumelana kufanele kukhethwe ngokujwayelekile ngokulinganisa kwamandla 1-2 izikhathi eziphakeme kunamandla adliwayo esifundeni.Ukukhetha okunjalo akunakuqinisekisa ukusebenza okuzinzile komphikisi, kepha futhi kuthuthukisa ukuthembeka kwalo lonke umjikelezo.
Ukukhetha ukuphambuka okuvumelekile: ukuphambuka okuvumelekile kungukuphambuka okuvuselelwa okuphezulu kwenani langempela lokumelana nenani lokuphikiswa okuvela kunani lokumelana nalo.Le pharamitha ibonisa ukunemba komkhiqizo.Ukuthola okujwayelekile kungu-5%, 1%, 0.5%, 0.1%, kanye ne-0.01%.Ezimweni ezihlukile zohlelo lokusebenza, ukubekezelela okufanele kufanele kukhethwe ngokuya ngezidingo zangempela.Isibonelo, lapho kudingeka khona ukulawulwa okuphezulu okuphezulu, kubalulekile ukukhetha imisakazo ngokubekezelelana okuphansi.
Ukucatshangelwa kwe-voltage ephezulu yokusebenza: I-voltage ephezulu yokusebenza ibhekisa ku-voltage ephezulu kakhulu ukuthi umphikisi akwazi ukumelana nokuhlinzwa isikhathi eside ngaphandle kokulimala ngokweqile noma ukulimala kukagesi.Uma i-voltage idlula leli nani elicacisiwe, lingadala izinhlansi zangaphakathi, umsindo, futhi zilimaze umphikisi.Ngakho-ke, lapho ukhetha umphikisi, kubalulekile ukuqinisekisa ukuthi amandla awo aphezulu okusebenza ahlangana noma adlula izidingo zesifunda.
Ukucatshangelwa kokuhlasela: Ukuhlanza izingalo isilinganiso sekhono lokuphikisana nokushintsha ngenani lokumelana ngaphansi kwezimo zangaphandle ezihlukile (njengokushisa, umswakama, amavolumu, isikhathi, izici zomthwalo, njll.).Ukuhlaselwa komphikisi kubalulekile ekuqinisekiseni ukuqina kanye nokwethenjwa kwesifunda.
Ithonya Lamandla Electromotive Force: Kumasekethe ajwayelekile, amandla omsindo wokumelana nabameli be-electromotive ajwayele ukunganakwa, kepha ezinhlelweni ezibuthakathaka zesiginali, lesi sici ngeke sinakwa.Umsindo we-wirewound amelana nomsindo we-thermal ikakhulukazi, kanti abaphikisayo wefilimu abancane nabo banomsindo wamanje ngaphezu komsindo we-thermal.Le misindo ihlobene nokumelana, izinga lokushisa kanye nokuvama kwama-band we-voltage yangaphandle, futhi idinga ukucatshangelwa okukhethekile lapho uhlela amasekethe abucayi.
Ukuhlolwa kwezimpawu eziphakeme kakhulu: lapho kusetshenziswa imivimbo ezindaweni ezivame ukuvezwa, imiphumela yazo yokungena kanye nokukhohlisa kudinga ukucatshangelwa.Emathendeni aphezulu, i-resistor iziphatha njengesifunda esilinganayo esinokumelana kwe-DC ngochungechunge ngokungenisa okusatshalaliswa bese kufana nokusakazwa kwekhono.Ukumelana okungewona ama-wirewound kanye nokumelana nokuwina kwabantu baziphatha ngendlela ehlukile kulokhu.Ukumelana kwe-wirewound kungenzeka kube nokungapheli okuphezulu ezindaweni ezivame ukuvelela, okubangela amandla abalethe kudlula amandla aphansi, okwandisa ubungozi bokushiswa..Ngakho-ke, ukukhetha okulungile kohlobo lokuphikisa kubalulekile kwizicelo ezivame kakhulu.
