Nyob hauv NPN transistor, tam sim no ntws los ntawm tus sau (C) mus rau Emitter (E), whereas hauv PNP transistor, tam sim no ntws los ntawm cov emitter mus rau tus sau. … Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm PNP transistor yog xws li tias thaum tam sim no tshwm sim ntawm lub hauv paus davhlau ya nyob twg ntawm lub transistor, ces lub transistor kaw OFF.

PNP transistors ua haujlwm li cas?

Kev txhais: PNP transistor yog ib hom transistor uas ib hom n-hom khoom yog doped nrog ob hom p-hom khoom. … Tam sim no nyob rau hauv ib tug PNP transistor ntws los ntawm lub emitter mus rau lub collectorQhov voltage xav tau los ntawm lub transistor lub emitter, collector thiab puag yog qhia los ntawm tsab ntawv ntawm PNP transistor.

Qhov txawv ntawm PNP thiab NPN transistor yog dab tsi?

Raws li lawv ib txwm raug xa mus, PNP thiab NPN sensors yog ob qho tib si nkag nrog lub zog zoo thiab tsis zoo, tom qab ntawd tsim lub teeb liab los qhia "rau" xeev PNP sensors tsim ib qho Cov txiaj ntsig zoo rau koj cov kev lag luam tswj cov tswv yim, thaum NPN sensors tsim cov teeb liab tsis zoo thaum lub xeev "on ".

NPN transistor ua haujlwm li cas?

NPN transistor yog tsim kom dhau electrons los ntawm cov emitter mus rau lub collector(yog li cov pa tam sim no ntws los ntawm cov khoom xa mus rau emitter). Lub emitter "emits" electrons rau hauv lub hauv paus, uas tswj cov xov tooj ntawm electrons lub emitter emits.

Kuv puas tuaj yeem siv PNP hloov NPN?

Teb: NPN thiab PNP transistors yog hloov pauv tauyog tias koj nco qab ib txoj cai yooj yim: Lub transistor bipolar yog qhov tseem ceeb ntawm ob lub rov qab-rau-rov qab diodes nrog lub hauv paus yog qhov sib txuas. … Ntawm sab laug yog NPN (tsis zoo-zoo-tsis zoo) transistor thiab sab xis yog PNP (positive-negative-positive) transistor.
