Teb: NPN thiab PNP transistors yog hloov pauv tau yog 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. … Sab laug yog NPN (tsis zoo-positive-negative) transistor thiab sab xis yog PNP (positive-negative-positive) transistor.
Peb puas tuaj yeem hloov NPN transistor nrog PNP?
Feem ntau, PNP transistor tuaj yeem hloov NPN transistors nyob rau hauv feem ntau cov hluav taws xob circuits, qhov sib txawv tsuas yog cov polarities ntawm qhov voltages, thiab cov lus qhia ntawm qhov tam sim no ntws. PNP transistors kuj tseem siv tau los ua cov khoom siv hloov pauv thiab ib qho piv txwv ntawm PNP transistor hloov tau qhia hauv qab no.
Puas yog NPN thiab PNP transistor tib yam?
Ib NPN transistor muaj ib daim ntawm P-hom silicon (lub hauv paus) sandwiched ntawm ob daim N-hom (tus sau thiab emitter). Hauv PNP transistor, hom txheej txheej yog thim rov qab. … NPN thiab PNP transistors muaj cov cim schematic zoo sib xws Qhov txawv tsuas yog qhov kev taw qhia ntawm xub ntawm tus emitter.
Kuv yuav ua li cas hloov PNP rau NPN?
Yog tias koj muaj qhov tseeb NPN sib npaug koj tsuas yog yuav tsum tau teeb tsa lub voj voog raws li nws tau kos, kom lub hauv paus, cov khoom siv thiab cov emitter terminals ntawm NPN txuas nrog qhov twg lub hauv paus, cov khoom sau thiab emitter ntawm PNP yuav tsum mus, thiab ces reverse lub hwj huam mov polarity.
PNP lossis NPN transistor twg zoo dua?
Yog li cov lus teb raug yog n-p-n transistors yog qhov nyiam rau p-n-p transistors vim tias cov hluav taws xob muaj zog dua li qhov thiab yog li kev txav ntawm lub zog siab.
