R yog cov khoom tiv thaiv, L yog Inductive thiab C yog Capacitive. thiab hauv C tivthaiv, lub kaum sab xis ntawm qhov tam sim no thiab voltage vectors yog + 90 deg i.e. tam sim no vector coj lub voltage vector los ntawm 90 deg.
Ua li no, theem kev sib raug zoo ntawm qhov hluav taws xob thiab tam sim no hauv LR Circuit Court yog dab tsi?
Nyob rau hauv ib tug resistor tam sim no thiab avoltages yeej ib txwm nyob rau hauv theem lub a theem lub kaum sab xis ntawm 0 °. Rau kev sib xyaw ntawm CR lub LR circuits , theem lub kaum sab xis yuav yog> 0 ° thiab < 90 ° (piv txwv li cov hlau lead rau CR thiab lag rau LR ntawm tam sim no w.r.t hluav taws xob ).
Ib tug kuj yuav nug, dab tsi yog theem kev sib raug zoo ntawm VS thiab kuv? Raws li qhov zaus ntawm qhov voltage, v thiab tam sim no, kuv yog tib yam lawv yuav tsum tau ncav cuag lawv qhov siab tshaj plaws qhov zoo, tsis zoo thiab xoom qhov tseem ceeb thaum lub sij hawm ua tiav ib zaug (txawm tias lawv cov amplitudes yuav txawv). Tom qab ntawd ob qhov sib hloov ntau, v thiab kuv tau hais tias yog hauv- theem ”.
Raws li txoj cai, koj yuav pom lub kaum sab xis ntawm RL Circuit Court li cas?
Series RL Circuit Analysis
- Txij li thaum tus nqi ntawm zaus thiab inductor paub, yog li ua ntej xam tus nqi ntawm inductive reactance XL: XL = 2 π fL os.
- Los ntawm tus nqi ntawm XL thiab R, xam tag nrho impedance ntawm lub Circuit Court uas muab los ntawm.
- Xam tag nrho theem kaum rau lub Circuit Court θ = tan – 1(XL/R).
Dab tsi yog theem kaum hauv AC Circuit Court?
Theem . Cov theem Qhov sib txawv yog <= 90 degrees. Nws yog kev cai siv lub lub kaum sab xis los ntawm qhov voltage ua rau tam sim no. Qhov no ua rau muaj qhov zoo theem rau inductive circuits vim tam sim no lags qhov voltage hauv ib inductive Circuit Court . Cov theem yog tsis zoo rau ib tug capacitive Circuit Court vim qhov tam sim no coj qhov voltage.

Nws txhais li cas thaum kev sib raug zoo ntawm kev sib raug zoo ua kev cuam tshuam?
Kev sib raug zoo ntawm ob tus neeg uas txhua tus neeg nyob ntawm thiab tau txais kev txhawb zog, txawm tias muaj txiaj ntsig lossis kev puas tsuaj, los ntawm lwm tus. ib qho kev sib cuam tshuam lossis kev sib raug zoo ntawm ob tus neeg, pab pawg, thiab lwm yam
Dab tsi yog qhov kev sib raug zoo ntawm kev ua lej ntawm qhov kev nyuaj siab khov kho thiab Mollality?
Kev nyuaj siab qhov chaw khov kho yog cov cuab yeej sib koom ua ke pom hauv cov kev daws teeb meem uas tshwm sim los ntawm kev qhia txog cov kuab tshuaj molecules rau cov kuab tshuaj. Cov ntsiab lus khov ntawm cov kev daws yog tag nrho qis dua li cov kuab tshuaj ntshiab thiab yog ncaj qha proportional rau molality ntawm cov kuab tshuaj
Dab tsi yog txoj hauv kev zoo li kev tshawb fawb thiab kev sib raug zoo?
Qhov zoo sib xws ntawm natural science thiab social sciences yog ob qho tib si saib cov xwm txheej tshwj xeeb. Tab sis kev soj ntsuam rau social scientist tuaj yeem muab faib ua kev soj ntsuam, nug cov lus nug, kawm cov ntaub ntawv sau. Tab sis tus kws tshawb fawb ntuj tsis tuaj yeem siv cov kev no
Dab tsi yog kev sib raug zoo ntawm biotic thiab abiotic Cheebtsam?
Abiotic Cheebtsam tso cai rau cov biotic muaj nyob. Abiotic Cheebtsam yog lub hnub thiab dej thiab cov as-ham hauv av. Biotic Cheebtsam yog cov nroj tsuag uas siv cov khoom siv abiotic thiab cov tsiaj uas noj cov nroj tsuag thiab cov tsiaj uas noj cov tsiaj
Dab tsi yog kev sib raug zoo ntawm sab nrauv thiab sab hauv lub kaum sab xis ntawm daim duab peb sab?
Cov kaum sab hauv yog hu ua Sab hauv cov ces kaum. Cov lej ntawm cov kaum sab hauv ntawm daim duab peb sab yog ib txwm 180 degrees. Lub kaum sab nrauv yog lub kaum sab xis ntawm ib sab ntawm ib qho duab, thiab ib txoj kab txuas ntxiv los ntawm sab tom ntej. Qhov sib npaug ntawm lub kaum sab nrauv thiab nws lub kaum sab hauv uas nyob ib sab kuj yog 180 degrees
