Uma ufuna indlela ephelele yokuthuthukisa izinto zikagesi ongase uthande ukucabangela aithubhu elilodwa lokumelana.Lezi zivame ukusetshenziswa ekuhlolweni kwesifunda nokuklama.Zingasetshenziselwa izinhlelo zokusebenza eziningi ezahlukene ezifana, amandla, okwamanje, i-voltage, ukumelana, ukuvuza kwamanje nokunye.Uma ufuna la mashubhu udinga ukuqinisekisa ukuthi uthola elifanele lesicelo sakho.Kunezinhlobo eziningana ezahlukene, kuhlanganise;i-bipolar, i-pentode, i-triode njalonjalo.
Isizathu sokuthi kungani ishubhu le-bipolar lidume kakhulu kungenxa yokuthi kulula ukusethwa nokusetshenziswa kwe-electronics.Lokhu kungenxa yokuthi abadingi noma yiluphi uhlobo lwamakhondatha angaphandle noma izinto zokwakha ukuze baqedele umjikelezo.Esikhundleni salokho, bangama-conductor alula nje adonsa futhi aguqule amandla emazingeni abo kagesi afanele.Ngakho-ke noma ungenalo ulwazi oluningi nge-electronics noma ungazi ukuthi wenzani, kulula ukukumisa lokhu.Uvele uxhume amatheminali okokufaka emiphumeleni yawo ehambisanayo.
Uma ubheke ukuguqula isilinganiso samandla esiphezulu sibe izilinganiso ezincane, khona-ke ishubhu ye-pentode izokunikeza inketho engcono kakhulu.Angelinye lamashubhu ajwayeleke kakhulu okulinganisa amandla aphezulu ngoba afika ngezinhlobonhlobo ezinkulu zosayizi abahlukene.Inzuzo enkulu kulawa mashubhu ukuthi asebenza kahle ngendlela emangalisayo ekuguquleni ugesi ube amandla emishini.Azidingi noma yiluphi uhlobo lwemicu noma ezinye izinto futhi lokhu kuzenza kube lula kakhulu ukuzifaka.Ingafakwa futhi ukusuka phezulu kuya phansi okuyinketho uma ungenankinga nokubhoboza izimbobo ezithile.
Esinye sezizathu zokuthi kungani amashubhu e-pentode esetshenziswa kakhuluithubhu elilodwa lokumelanas kungenxa yokuthi ashesha kakhulu futhi anembe.Bayakwazi ukwenza umsebenzi wenziwe ngokushesha okukhulu kunanoma yiluphi olunye uhlobo oluvamile lweshubhu.Bayakwazi futhi ukusebenzisa okupholile kakhulu ngenxa yokuthi ingxenye yabo yefeni yokupholisa itholakala ngaphansi kwedivayisi ngokwayo epholisa izingxenye ngempumelelo kakhulu.Enye inzuzo kulawa mashubhu ukuthi ngokuvamile anezikhonkwane ezincane zokuhlanekezela okusho ukuthi azwakala emuhle nakuba izinga lesiginali lingekho phezulu ngendlela ebelingaba ngayo.
Uma ubheka ukusebenzisa ishubhu ku-amplifier noma enye insiza ye-elekthronikhi enamandla amakhulu ngakho-ke kubalulekile ukuthi wazi kahle ukuthi yini obhekene nayo.Kunezinhlobo eziningana zamashubhu ahlanganisa i-bipolar, i-pentode kanye nokushintsha.Kufanele ngaso sonke isikhathi ukhethe okulungile kuhlelo oluhlosiwe ngakho qiniseka ukuthi uyalwenza ucwaningo lwakho.Ngale ndlela ngeke kudingeke ukhathazeke ngokulimaza noma yiziphi izingxenye lapho usebenzisa uhlobo olungalungile lweshubhu.
Uma ufuna ukuthenga aithubhu elilodwa lokumelanakuphrojekthi yakho, qiniseka ukuthi ubuza umthengisi ukuthi yiluphi uhlobo lweshubhu olungalungela isicelo.Bazokwazi ukukunikeza umbono omuhle ngokusekelwe ezidingweni zakho kanye nokusekelwe kulokho abanye abasanda kukuthenga.Lokhu kuzosiza ukuqinisekisa ukuthi uthola umkhiqizo ofanele izidingo zakho.Qiniseka ukuthi uthola lonke ulwazi oludingayo ngaphambi kokwenza noma yikuphi ukuthenga ukuze ukwazi ukwenza isinqumo esinolwazi mayelana nokuthenga.
