Qee cov qauv ntawm cov ntawv ntsuas tau nruab nrog cov ntsuas tsim hluav taws xob rau qhov nce ntawm lub zog hluav taws xob transistors. Yog tias koj tsis muaj lub cuab yeej zoo li no, tom qab ntawd cov kab ke kev noj qab haus huv tuaj yeem tshawb xyuas nrog cov kev sim siv sib piv hauv ohmmeter hom, lossis siv digital tester hauv diode kuaj hom.
Cov Lus Qhia
Kauj ruam 1
Txhawm rau kuaj bipolar transistors, txuas ib qho kev sojntsuam ntawm qhov loj mus rau lub hauv paus ntawm transistor, nqa lub ntsuas zaum thib ob hloov mus rau emitter thiab tus sau khoom, tom qab ntawd hloov cov kev ntsuas thiab rov ua cov qub. Thov nco ntsoov tias sab hauv cov hluav taws xob ntawm ntau cov digital lossis muaj zog transistors muaj peev xwm muaj kev tiv thaiv diodes ntawm tus neeg sau thiab cov emitter thiab cov kab hluav taws xob hauv nruab nrab ntawm lub hauv paus thiab emitter lossis hauv puag ncig, yog tias koj tsis paub txog qhov no, tom qab ntawv yuam kev koj tuaj yeem xav txog qhov khoom no yam tsis zoo.
Kauj ruam 2
Thaum kuaj cov hloov transistors teb, nco ntsoov qhov tseeb tias lawv tuaj nyob hauv ntau hom. Piv txwv, kuaj cov transistors nrog lub rooj vag raws pn-hlauv thaiv txheej txheej yog nqa tawm raws li hauv qab no. Nqa cov pointer dog dig ohmmeter lossis digital (thib ob yog yooj yim dua).
Kauj ruam 3
Ntsuas qhov tsis kam ntawm qhov nqos dej thiab qhov chaw tawm, nws yuav tsum me me thiab kwv yees li sib npaug hauv ob qho kev qhia. Tam sim no ntsuas mus rau pem hauv ntej thiab rov qab tsis kam ntawm qhov kev sib tshuam, rau qhov no, txuas cov khoom siv mus rau lub rooj vag thiab ntws (lossis qhov chaw). Yog tias tus transistor ua tau zoo, qhov thev yuav txawv ntawm ob qho kev qhia.
Kauj ruam 4
Thaum koj txheeb xyuas qhov kev tawm tsam ntawm qhov dej ntws thiab qhov chaw, tshem tawm qhov them nyiaj ntawm lub rooj vag, rau qhov no, kaw nws nrog qhov chaw li ob peb lub vib nas this, yog tias qhov no tsis ua tiav, koj yuav tau txais qhov tshwm sim uas tsis rov ua dua. Feem ntau cov hwj huam them ua teb muaj transistors tsis tshua muaj neeg zoo nkauj. Yog li no, ua ntej koj nqa cov transistor rau hauv koj txhais tes, nco ntsoov tias tsis muaj nqi ntawm koj lub cev. Txhawm rau tshem ntawm lawv, kov txhua yam khoom siv nrog koj txhais tes (lub roj teeb ua cua sov yuav ua). Cov cuab yeej muaj zog ua haujlwm transistors feem ntau nruab nrog kev tiv thaiv zoo li qub, tab sis txawm tias qhov no, kev tiv thaiv thaum ua haujlwm nrog lawv kuj yuav tsis puas.
