Thaum BJT nyob rau hauv qhov saturation, Vce (sat) txhais tau tias qhov sib txawv ntawm qhov sib txawv ntawm Tus Sau thiab Emitter ntawm spec. "Ic" tam sim no tus nqi. Tus nqi ntawm Vce(sat) muaj kev cuam tshuam rau Ic(sat) thiab tus neeg sau tsis kam "rc ".
VCE npaum li cas thaum lub transistor saturated?
"Saturation" hauv lub transistor hloov hluav taws xob tau ua tiav thaum qhov hluav taws xob hla cov khoom sau / emitter (VCE (sat)) yog tsawg dua lossis sib npaug. 1 rau. 3 volts - nyob ntawm seb hom transistor.
VCE yog dab tsi?
Xaiv Vce siv lub formula Vce=Vcc - [Ie(Rc + Re)]. Siv cov lej los ntawm cov piv txwv yav dhau los, qhov sib npaug ua haujlwm raws li hauv qab no: Vce=12 - 0.00053 (3000 + 7000)=12 - 5.3=6.7 volts.
Vim li cas Vce zaum 0.2 V?
Nws yog vim ob qho tib si hauv cov transistor yog rau pem hauv ntej ntawm kev saturation. Nyob rau hauv cov xwm txheej no, rau npn transistor lub emitter rau lub hauv paus voltage yog ~ + 0.7V thiab tshaj ntawm lub hauv paus mus rau collector ~ 0.5V (base p, collector n).
VCE yog dab tsi ntawm ntug kev saturation?
vim peb siv VCE =0.3 V ntawm ntug kev saturation thiab | Chegg.com.

Ntawm qhov taw tes saturation mu ntawm cov khoom yog?
Thaum TU yog siab tshaj plaws hu ua saturation point MU yog zero Units ntawm cov khoom yog 1. Thaum Marginal Utility yog xoom, Total Utility yog siab tshaj . MU yog dab tsi ntawm taw tes ntawm saturation? Saturation point yog taw tes uas MU yog xoom thiab TU yog qhov siab tshaj plaws, txawm li cas los xij, kev noj tom qab saturation taw tes ua rau poob hauv TU, thaum MU ua tsis zoo .
Tus me nyuam mos oxygen saturation yog dab tsi?
Nws tau lees paub tias lub sijhawm noj qab haus huv ntawm cov menyuam mos ua pa hauv chav cua muaj cov pa oxygen saturation ntawm 95% lossis ntau dua, zoo ib yam li cov neeg laus (Levesque 2000). Cov ntshav oxygen saturation yuav tsum ua tib zoo sib npaug rau cov menyuam mos uas yug ntxov ntxov .
Qhov kev saturation yog qhov zoo tshaj?
2: SATURATION III Tom qab tso ob albums, SATURATION III yog txoj hauv kev zoo tshaj plaws uas Brockhampton tuaj yeem xaus lawv cov trilogy. Tawm ntawm peb, qhov kev tsim tawm album no yeej ua rau nws muaj suab npe tshwj xeeb tshaj plaws . Brockampton saturation yog dab tsi?
Ntawm qhov chaw saturation marginal utility ntawm cov khoom yog?
Marginal utility ntawm ib yam khoom ntawm qhov chaw ntawm saturation implies lub ntsiab lus tom qab uas kev noj ntau units ntawm cov khoom yuav tsis muab rau cov neeg siv khoom txaus siab. Qhov no yog vim hais tias ntawm lub sijhawm no, cov khoom siv marginal muab los ntawm chav tsev kawg uas tus neeg siv khoom siv yog zero Thaum twg saturation point yog mus txog marginal utility ntawm ib tug zoo ua?
Puas yog oxygen saturation tsawg nrog lub plawv nres?
Cov neeg mob uas mob me mus rau nruab nrab mob plawv tsis ua hauj lwm yuav qhia tau tias txo qis hauv oxygen saturation, hos cov neeg mob uas mob plawv tsis ua hauj lwm yuav muaj oxygen desaturation heev, txawm nyob rau ntawm so. Pulse oximetry tseem muaj txiaj ntsig rau kev saib xyuas tus neeg mob cov lus teb rau cov pa oxygen ntxiv thiab lwm yam kev kho mob .
