Vth yog xam los ntawm kev qhib lub davhlau ya nyob twg. Siv qhov hluav taws xob faib hluav taws xob, Vth=210 / (2 + 1)=6.67V … Piav qhia: Thevenin's theorem hais tias kev sib xyaw ntawm cov khoom siv hluav taws xob, qhov chaw tam sim no thiab cov resistors sib npaug rau ib leeg. Voltage qhov chaw V thiab ib tug series resistor R. 8.
Vth nyob qhov twg hauv Thevenin's theorem?
Cov txheej txheem rau kev tshuaj xyuas DC Circuit Court siv Thevenin's Theorem yuav tsum muaj cov kauj ruam hauv qab no:
- Nrhiav Thevenin Resistance los ntawm kev tshem tawm tag nrho cov khoom siv hluav taws xob thiab thauj khoom resistor.
- Nrhiav Thevenin Voltage los ntawm ntsaws rau hauv qhov voltages.
- Siv Thevenin Resistance thiab Voltage txhawm rau nrhiav qhov tam sim no ntws los ntawm kev thauj khoom.
VTH thiab RTH yog dab tsi hauv Thevenin theorem?
Thévenin's theorem yog cov txheej txheem uas lub voj voog nyuaj raug txo mus rau qhov sib npaug ntawm Circuit Court uas muaj ib qho hluav taws xob ib leeg (VTH) hauv cov koob nrog ib qho kev tawm tsam (RTH) thiab kev thauj khoom tsis kam (RL) … Lub theorem kuj pab xaiv qhov zoo tshaj plaws tus nqi ntawm lub load (tsis kam) rau siab tshaj plaws hloov fais fab.
Yuav ua li cas rau Vth?
Qhov qhib-circuit voltage / luv-circuit tam sim no mus kom ze yuav siv tau los xam cov Thevenin sib npaug rau ib tug paub Circuit Court. Qhib-circuit voltage - Siv txhua txoj kev uas koj nyiam. Peb yuav siv node voltage hauv qhov no. =12 V VTh=voc=12 V.
Puas Thevenin voltage zoo?
Yes. Nws nyob ntawm seb koj txhais li cas cov kev taw qhia ntawm qhov zoo voltage nyob rau hauv koj qhov sib npaug voltage qhov chaw. Hauv lwm lo lus, yog tias koj hloov txoj haujlwm ntawm "+" thiab "-" ntawm daim duab kos, lub cim ntawm qhov hluav taws xob yuav hloov.
