Qhov yooj yim RC Circuitual muaj cov resistors thiab capacitors txuas nrog cov koob thiab siv los ntawm cov khoom siv hluav taws xob uas muaj ntau. Vim yog cov kab kev sib txuas ntawm capacitors thiab resistors, zoo li qub ntws los ntawm lawv. Qhov voltage ntawm capacitor vc thiab resistor VR yog sib tshuam rau ib leeg hauv daim duab. Lawv tag nrho cov lej ib txwm muaj ntau dua li tag nrho cov hluav taws xob ntawm V.
Lub vector daim duab ntawm aSeries keeb kwmRC Circuit qhia tau tias kev lag luam tam sim no tag nrho cov hluav taws xob tag nrho los ntawm lub kaum sab xis ntawm 0 txog 90 degrees. Thov nco ntsoov tias yog koj luv scrcuitaccuit lub resistor, lub kaum ntse ntse lub caccuitacit), thiab yog tias koj luv nqi (lub kaum ntse ntse) yog 0℃(ntshiab (ntshiab nquag load).
Lub impedance ntawm aSeries keeb kwmRC Circuit Zoo li sab saud nyob rau hauv ib lub vector daim duab, qhov twg cov nquag Resistor R yog nyob rau ntawm kab rov tav thiab reactance xc yog nyob ntawm kab laum. Lub hypotenuse ntawm cov cim peb lub kaum sab xis kaum yog lub impedance ntawm Circuit Court, thiab theem kaum yog lub kaum sab xis ntawm cov kab rov tav thiab cov impedance vector.
Lub theem kaum sab sib txawv ntawm 0℃rau cov kev hloov kho ntshiab rau -90℃rau cov hluav taws xob ntshiab. Los ntawm cov kev ntxhov siab peb sab, peb tau txais:
Txiav txim siab theem kaum sab xis siv cov muaj nuj nqi inverse (tangency):
Hauv kev RL Circuit Court, tib qho tam sim no ntws los ntawm coil thiab resistor. Qhov voltage ntawm coil vc lags tom qab tag nrho tam sim no los ntawm 90 degree, thiab lub voltage ntawm lub resistor yog nyob rau hauv theem nrog tam sim no. Raws li Kirchhoff txoj cai thib ob (rau voltage), tus lej ntawm voltage dauv hla cov cheeb tsam Circuit Coents yuav tsum muaj sib npaug rau tag nrho voltage vt. Qhov voltage ntawm resistor VR thiab Capacitor VC yog 90 qhov tawm ntawm theem, yog li lawv tau ntxiv ua ke siv vector kosram, thiab tag nrho cov hluav taws xob yog txiav txim siab los ntawm cov hauv qab no:
Thov nco ntsoov tias tag nrho cov hluav taws xob tag nrho yog ib txwm tsawg dua li cov lej ntawm cov distor thiab coil, ib yam li ib txwm kaum peb lub kaum sab xis ib txwm muaj tsawg dua li cov ceg ntawm ob txhais ceg.
