Capacitive reactance
Ib qho hluav taws xob DC siv thoob plaws a capacitor ua rau zoo them rau sau rau ntawm ib sab thiab tsis zoo them rau sau rau ntawm lwm sab; lub teb hluav taws xob vim yog cov khoom siv hluav taws xob yog qhov kev tawm tsam ntawm qhov tam sim no.
Kuj tseem paub yog, puas yog qhov tsis kam lossis capacitance puas tsis zoo?
Cov tsis kam tsis muaj ib tsis zoo kos npe, tab sis lub impedance tuaj yeem. Lub impedance ntawm a capacitor yog sib npaug rau -j/(wC), qhov C yog tus capacitance thiab w yog zaus zaus 2 * pi. Lub impedance ntawm a capacitor yog sib npaug rau -j/(wC), qhov C yog tus capacitance thiab w yog zaus zaus 2 * pi.
Ib yam li ntawd, dab tsi yog qhov capacitive reactance? Capacitive reactance (symbol XC) yog qhov ntsuas ntawm a cov capacitor tawm tsam rau. AC (alternating tam sim no). Zoo li kev tiv thaiv nws yog ntsuas hauv ohms, tab sis. reactance yog qhov nyuaj tshaj qhov tsis kam vim nws tus nqi nyob ntawm qhov. zaus (f) ntawm lub teeb liab hluav taws xob hla lub capacitor ib yam nkaus.
Tsis tas li ntawd, cov capacitors puas muaj qhov tsis zoo impedance?
Hauv ELECTRONICS, ob leeg CAPACITORS THIAB INDUCTORS YOG POSITIVE IMPEDANCE Thaum nyob hauv ELECTROTECHNICS, CAPACITORS muaj qhov tsis zoo TAB SIS INDUCTORS YOG POSITIVE IMPEDANCE . Tom qab ntawd, qhov hluav taws xob poob tshwm sim thoob plaws capacitors thiab inductors; lawv hloov nyob rau hauv ib tug txawv (tawm tsam) txoj kev los ntawm lub sij hawm tab sis ob leeg lawv yog voltage tee.
Dab tsi yog capacitive thiab inductive reactance?
REACTANCE . Cov nyhuv ntawm inductive reactance yog ua kom tam sim no lag lub voltage, thaum uas capacitive reactance yog ua kom tam sim no coj cov voltage.

Puas yog gal4 protein nyob rau hauv cov poov xab ua tau zoo lossis tsis zoo ntawm GAL noob?
Gal4 transcription yam yog ib tug zoo regulator ntawm noob qhia ntawm galactose-induced noob. Cov protein no sawv cev rau tsev neeg loj ntawm cov kab mob ntawm cov kab mob, Gal4 tsev neeg, uas suav nrog ntau dua 50 tus tswv cuab hauv cov poov xab Saccharomyces cerevisiae xws li. Oaf1, Pip2, Pdr1, Pdr3, Leu3
Puas yog Gram zoo lossis tsis zoo txaus ntshai?
Hauv kev sib piv rau Gram zoo, cov kab mob Gram-negative muaj kev phom sij ntau dua li cov kab mob, vim muaj cov tshuaj ntsiav los yog cov slime txheej uas npog lub txheej membrane. Ua raws li txoj kev no, cov kab mob micro tuaj yeem nkaum nws cov antigens saum npoo uas yuav tsum tau ua rau tib neeg lub cev tiv thaiv kab mob
Puas yog tib neeg lub hlwb Gram zoo lossis Gram tsis zoo?
Tib neeg lub hlwb tsis muaj cov phab ntsa ntawm tes lossis Peptidoglycan (PDG). Cov hlwb tuaj yeem coj cov xim stain. Ib qho ntawm koj cov neeg koom tes hauv chav kuaj tau ua raws li cov txheej txheem pom zoo ntawm kev khiav Gram-positive thiab Gram-negative tswj kab mob ntawm nws Gram stain ntawm ib hom tsis paub
Dab tsi yog tag nrho series capacitive reactance mis?
Nyob rau hauv capacitors, tam sim no coj voltage los ntawm 90 degrees. Cov mis rau kev xam cov Capacitive Reactance, los yog impedance ntawm lub capacitor yog: Capacitive reactance, denoted as x sub c (XC), yog sib npaug rau qhov tas li ib lab (los yog 106) muab faib los ntawm cov khoom ntawm 2p (los yog 6.28) zaus zaus lub sij hawm lub capacitance
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
