Ngati mukuyang'ana njira yabwino yopititsira patsogolo zamagetsi mungafune kuganizira achubu chokana chimodzi.Izi zimagwiritsidwa ntchito poyesa kuzungulira ndi kupanga.Atha kugwiritsidwa ntchito pazinthu zosiyanasiyana monga, mphamvu, zamakono, magetsi, kukana, kutayikira kwapano ndi zina.Mukamayang'ana machubuwa muyenera kuwonetsetsa kuti mwapeza yoyenera pakugwiritsa ntchito kwanu.Pali mitundu ingapo yosiyanasiyana, kuphatikiza;bipolar, pentode, triode ndi zina zotero.
Chifukwa chomwe chubu cha bipolar chimatchuka kwambiri chifukwa ndi chosavuta kukhazikitsa ndikugwiritsa ntchito pamagetsi.Izi ndichifukwa choti safuna ma conductor akunja kapena zida kuti amalize kuzungulira.M'malo mwake, ndi ma conductor osavuta omwe amakoka ndikusintha mphamvu kukhala ma voltage awo.Chifukwa chake ngakhale mulibe chidziwitso chochuluka ndi zamagetsi kapena simukudziwa zomwe mukuchita, ndizosavuta kukhazikitsa izi.Mukungolumikiza ma terminals olowera pazotsatira zawo.
Ngati mukufuna kusintha mphamvu yapamwamba kukhala miyeso yaying'ono, ndiye chubu cha pentode chidzakupatsani njira yabwino kwambiri.Iwo ndi amodzi mwa machubu odziwika bwino amphamvu kwambiri chifukwa amabwera mosiyanasiyana mosiyanasiyana.Phindu lalikulu la machubuwa ndikuti ndiabwino kwambiri pakusintha magetsi kukhala mphamvu zamakina.Iwo safuna mtundu uliwonse wa filaments kapena zipangizo zina ndipo izi zimawapangitsa kukhala zosavuta kukhazikitsa.Itha kukhazikitsidwanso kuchokera pamwamba mpaka pansi yomwe ili njira ngati mulibe vuto kuboola mabowo.
Chifukwa chimodzi chomwe machubu a pentode amagwiritsidwa ntchito kwambirichubu chokana chimodzis chifukwa amathamanga kwambiri komanso olondola.Amatha kugwira ntchitoyo mwachangu kuposa mtundu wina uliwonse wa chubu.Amathanso kuthamanga mozizira kwambiri chifukwa fani yawo yoziziritsa ili m'munsi mwa chipangizocho chomwe chimaziziritsa zigawozo bwino kwambiri.Phindu lina la machubuwa ndikuti nthawi zambiri amakhala ndi ma spikes ang'onoang'ono opotoza zomwe zikutanthauza kuti amamveka bwino ngakhale kuti siginecha sikukwera momwe ingakhalire.
Ngati mukuyang'ana kugwiritsa ntchito chubu mu amplifier kapena chipangizo china chamagetsi champhamvu kwambiri ndiye kuti nkofunika kuti mudziwe bwino zomwe mukuchita nazo.Pali mitundu ingapo yamachubu kuphatikiza bipolar, pentode ndi switching.Muyenera kusankha yoyenera nthawi zonse pazomwe mukufuna kuti mugwiritse ntchito kotero onetsetsani kuti mwachita kafukufuku wanu.Mwanjira iyi simudzadandaula za kuwononga zigawo zilizonse mukamagwiritsa ntchito mtundu wolakwika wa chubu.
Pamene mukuyang'ana kugula achubu chokana chimodzipa ntchito yanu, onetsetsani kuti mwafunsa wogulitsa mtundu wa chubu chomwe chingakhale choyenera kugwiritsa ntchito.Adzatha kukupatsani malingaliro abwino malinga ndi zosowa zanu komanso kutengera zomwe ena agula posachedwa.Izi zidzakuthandizani kuonetsetsa kuti mumapeza mankhwala oyenera pazosowa zanu.Onetsetsani kuti mwapeza zonse zomwe mukufuna musanagule kuti muzitha kupanga chiganizo mwanzeru pankhani yogula.
