Me pēhea te ki te tirohia i te transistor

I roto i te ao o te hangarau hou e kore e taea te mahi i waho transistors. haere mai ratou i roto i te whānuitanga o ngā pūrere hiko, e taea te kitea ratou i roto i waea, waerehe, rorohiko me waka. I te tahi taime i reira he he hiahia mo te whakaū o ratou mahi, a ka whai hua ki te mohio me pehea ki te tirohia i te transistor me e titau tenei. Ko te rauemi aroaro i roto i te tuhinga miramira te take.

Transistors me momo

Tenei pūrere Ko te pūrere hiko, whakamahia nei i roto i te tikanga ki te whakarei ake electroschemes tohu taketake. Kei te hanga te reira i ngā rauemi Semiconductor. E 2 ngā momo o transistors: mara ngaohiko me te pourua, kahore e whakahaeretia me nāianei. I tua atu, ka taea e waiho ratou kikokore, me te kaha, iti, me te auau teitei. rerekē ratou i roto i te rahi me te hoahoa o ngā whare.

E mea pinepine, no te lave ki te tikanga o transistors pourua ratou momo, kua hanga o germanium silicon ranei. E huaina ratou pourua no te mahi ratou ki irahiko (kawe tiaki) me rua. Ko tētahi o nga wāhi o te transistor kei i runga i te mata, ka karanga te kaituku, takawaenga - turanga, me te tahi atu, kei hoki i runga i te mata - tango. Mai te kawehiko 3 hangaia e PN whakawhiti 2: tikanga kaikohi i waenganui i te kaikohi me te turanga, me te kaituku hono nei te i waenganui i te kaituku me te turanga. pea te transistor o te "i runga i" āhua me te "atu", ka kawea te whakawhitinga i waenganui i a ratou i roto i na tikanga o tohu hiko.

Ko te transistors whakaaro matua - te whakatupuranga, amplification me te faafariuraa o oscillations hiko. Ko, rite tetahi pūrere hangarau, kia kore te transistor. Me koe ki te mohio me pehea ki te tirohia i te transistor ki te hua, ki te kia tika. Hoki tenei multimeters whakaaro.

Taki transistor hei whakamatau

Multimeter (aka Kaiwhakamātau) - ko te mea ngā motuhake, i nei whakahaere mahi hiko. fakatahai reira e rave rahi mahi: rite he iti fakatahai iahiko, ine ngaohiko, ohmmeter. He rua tairitenga me ngā pūrere mamati, marama, kawe me te pahoho, e fakatahai te rota o wāhitanga.

Mita - he pūrere e parau e founga ki tirohia te transistor me hanga mārama ai. Hei whakamatau faati'a te waea ki te ātete whanganga taiawhio iti, tangi te whakaoho, oro marama ranei.

I mua i ui ki te tukanga, me pehea ki te tirohia i te ia hei whakamatau transistor, he mea nui ki te mohio e wehea enei taputapu ki 2 momo rite ki te whakaritenga o ngā papa ki te kawe ia rerekē. Ko te kupu i reira e Semiconductors ki te kawe ia hiko (PnP), me Semiconductors p-momo (p-).

Hei whakamātau i te ātete o te whakawhitinga tika ki te turanga ki te hono i te "haunga" te mita me te ki te kaituku me te kaikohi i roto i tahuri hono "me". huri i te tūnga o te "tango" me "me" i roto i te inenga resistance whakamuri. Ki te whanganga i te ātete whakawhiti PnP faahiti te taua tukanga, engari preliminarily te huri wehenga tawhiti. I roto i te haki whakawhiti i te turanga ki te kaituku me te kaikohi me prozvanivatsya 1 anake taha.

Mai te multimeter ki tirohia taea te transistor e, engari e kore e hoatu i te reira i te taurangi tūturu o ngaue'aki o te pūrere, hoki kia whakahaere tino nui tona arotake i roto i te aratau hohe. I roto i tenei take, ka waiho atu pono te hua.

Na ano: me pehea ki te tirohia i te transistor me kia māia i roto i te hua? I roto i ngā pūrere pourua mō te haratau, ka taea e kitea e koe mo te ritenga ngōhiko ia o ona whakawhitinga, i muri i te taki ratou ngaue'aki. He transistors kaha e ngā waenganui i te kaituku me te kaikohi o te ngōhiko tinana pāhūhū, a i waenganui i te turanga, me te kaituku - he ārai tiaki. A, no te te mita i tetahi wehenga tawhiti tenei transistor ka hei te ātete o i toru ki te rima tekau ohms, me prozvanivatsya i waenganui kaituku me te kaikohi e reira rite te ngōhiko. e whakaatu ana tēnei ki te ngaue'aki o ngā wāhanga.
