A passive load yog a thauj muaj tsuas yog ib tug resistor, capacitor los yog inductor, los yog ib tug ua ke ntawm lawv. An active load yog a thauj uas suav nrog qee yam uas yog tam sim no lossis voltage tswj, tshwj xeeb yog cov khoom siv asemiconductor. Kuv cov qauv tsim hluav taws xob yuav tsum suav tias yog qhov kev sim.
Tsis tas li ntawd, dab tsi yog txhais los ntawm active load?
Hauv Circuit Design, ib active load yog ib tug circuitcomponent ua los ntawm nquag cov khoom siv, xws li transistors, npaj los nthuav qhia qhov siab me me-cim impedance tseem tsis tas yuav tsum muaj qhov loj DC voltage poob, raws li yuav tshwm sim yog tias lub resistor loj tau siv los hloov.
Vim li cas daim iav tam sim no siv los ua cov khoom hnyav? Ib qho tseem ceeb feature ntawm lub daim iav tam sim no islatively siab tso zis tsis kam uas yuav pab kom cov zis tam sim no tas li tsis hais txog thauj tej yam kev mob. Cov daim iav tam sim no feem ntau yog siv muab kev tsis ncaj ncees dej ntws thiab active loads hauv amplifierstages.
Tsis tas li ntawd, dab tsi yog active thiab passive load torque?
Active Load Torque yog cov lub zog uas muaj peev xwm tsav lub cev muaj zog raws li qhov sib npaug xws li: lub zog quab yuam, nro, compression thiab torsion thiab lwm yam Passive load torque yog cov lub zog uas yog ib txwm tawm tsam cov lus tsa suab thiab hloov lawv cov kos npe rau ntawm qhov thim rov qab ntawm kev txav xws li: Kev sib txhuam, windage, txiav thiab lwm yam.
Dab tsi yog active thiab passive tivthaiv?
Cov khoom xyaw nquag suav nrog amplifying cov khoom xws li transistors, triode nqus raj (valve), thiab qhov diodes. Passive Cheebtsam can't tintroduce net zog rau hauv Circuit Court. Passive Cheebtsam suav nrog ob lub davhlau ya nyob twg cov khoom xws li resistors, capacitor, inductors, thiab transformers.

Passive Transport Quizlet yog dab tsi?
Passive Thauj. kev txav ntawm cov ntaub ntawv hla lub cell membrane uas siv tsis muaj zog. Concentration Gradient. Qhov sib txawv ntawm qhov concentration ntawm cov kuab tshuaj ntawm ob sab ntawm daim nyias nyias. Molecules ib txwm txav los ntawm HIGH concentration mus rau qis concentration
Active load switching yog dab tsi?
1) Active load switching yog cov txheej txheem nyob rau hauv whichan active tivthaiv (cov khoom muaj peev xwm ntawm amplification andrectification) yog siv raws li ib tug load nyob rau hauv lub Circuit Court. Feem ntau siv Mosfets
Dab tsi yog passive diffusion hauv biology?
Kev thauj mus los tsis zoo yog qhov tshwm sim tshwm sim thiab tsis xav kom lub cell siv lub zog kom ua tiav qhov kev txav mus los. Hauv kev thauj mus los tsis zoo, cov tshuaj txav los ntawm thaj chaw siab dua mus rau thaj tsam ntawm qhov qis qis hauv cov txheej txheem hu ua diffusion
Dab tsi yog qhov txawv ntawm active thiab ib txwm galaxies?
Rau cov galaxies ib txwm, peb xav txog tag nrho lub zog uas lawv tso tawm raws li qhov sib npaug ntawm cov emission los ntawm txhua lub hnub qub pom hauv galaxy, tab sis hauv cov galaxies nquag, qhov no tsis muaj tseeb. Nyob rau hauv ib lub galaxy nquag, nws qhov supermassive dub yog accreting cov khoom los ntawm lub galaxy lub ntom ntom cheeb tsam
Puas yog sodium poov tshuaj twj tso kua mis active lossis passive?
Sodium-Potassium Pump. Cov txheej txheem ntawm kev txav sodium thiab potassium ions hla lub cell membrance yog ib qho kev thauj mus los uas cuam tshuam nrog hydrolysis ntawm ATP los muab lub zog tsim nyog
