RC cov kab hluav taws xob
Impedance: yog dab tsi qhov "Pom" raws li kev tawm tsam tag nrho rau tam sim no
Txoj hauv kev suav ntawm impedance txawv ntawm ib qho Circuit Court
Kauj ruam 1:
Thaum lub tshuab hluav taws xob tsuas yog muaj peev xwm (muaj lub tshuab hluav taws xob nkaus xwb), lub kaum sab xis ntawm qhov siv hluav taws xob thiab tag nrho tam sim no yog 90 ° (Tam sim no Leads)
Kauj ruam 2:
Thaum muaj kev sib xyaw ua ke ntawm ob qho kev tiv thaiv thiab lub peev xwm hauv Circuit Court, theem kaum sab xis ntawm kev tiv thaiv (R) thiab lub zog tiv taus (XC) yog 90 ° thiab lub kaum sab xis theem rau tag nrho cov impedance (Z) yog qhov chaw nruab nrab ntawm 0 ° thiab 90 °
Thaum muaj kev sib xyaw ua ke ntawm ob qho kev tiv thaiv thiab lub peev xwm hauv Circuit Court, theem kaum sab xis ntawm tag nrho tam sim no (IT) thiab lub zog hluav taws xob (VC) yog 90 ° thiab lub kaum sab xis theem ntawm qhov siv hluav taws xob (VS) thiab tag nrho tam sim no (IT) yog qhov chaw nruab nrab ntawm 0 ° thiab 90 °, nyob ntawm qhov txheeb ze qhov tseem ceeb ntawm kev ua haujlwm thiab lub peev xwm
Kauj Ruam 3: Voltage thiab Tam Sim No Phasor Daim Duab rau Waveforms
Kauj Ruam 4: Tam sim no, Kev Tiv Thaiv thiab Kev Siv Hluav Taws Xob Lub Sij Hawm ntawm Series RC Circuits
Kauj Ruam 5: Impedance thiab Phase Angle ntawm Series RC Circuits
- Hauv cov kab hluav taws xob RC series, tag nrho qhov cuam tshuam yog phasor sum ntawm R thiab Xc
- Impedance qhov ntau: Z = √ R^2 + Xc^2 (Vector sum)
- Theem kaum: θ = ziab-1 (X C/R)
Vim li cas peb thiaj siv cov lej vector tsis sib npaug algebraic?
Ans: Vim tias Kev Tiv Thaiv tsis ncua qhov hluav taws xob, tab sis Capacitor ua qhov ntawd.
Yog li, Z = R+Xc tsis raug.
Daim ntawv thov Ohm txoj cai rau tag nrho series RC Circuit cuam tshuam nrog kev siv ntau Z, Vs, thiab Itot raws li:
Itot = Vs/Z Z = Vs/Itot Vs = Itot * Z
Tsis txhob hnov qab:
Xc = 1/2πFC
Kauj Ruam 6: Kev hloov pauv ntawm Impedance Nrog Zaus
Kauj Ruam 7: Kev hloov pauv ntawm Impedance thiab Phase Angle Nrog Zaus
Kauj Ruam 8: Ib qho piv txwv ntawm Z thiab XC Hloov Li Cas
R tseem tsis tu ncua
