Yog li ntawd, tus naj npawb ntawm lub sijhawm tas li uas yuav dhau mus ua ntej cov hluav taws xob tam sim no hauv RC them thiab RC tso tawm hluav taws xob poob mus rau ib nrab ntawm nws cov nqi pib yog 0.69. Li no, qhov kev xaiv raug yog D.
Ntau npaum li cas lub sijhawm yuav dhau mus ua ntej lub zog?
Lub zog khaws cia ntawm qhov sib npaug yog: Piv txwv tias lub capacitor pib them ntawm t=0. Peb tsis lees txais qhov qub thaum lub capacitor pib them ntawm t=0. Li no, 1.23 lub sij hawm tas mus lirov.
Yuav siv sijhawm pes tsawg lub sijhawm kom them tag nrho?
Yog hais tias tus resistor txuas nrog hauv series nrog lub capacitor tsim ib qho RC Circuit Court, lub capacitor yuav them maj mam los ntawm tus resistor kom txog rau thaum qhov hluav taws xob hla nws mus txog qhov voltage mov. Lub sij hawm xav tau rau lub capacitor kom them tag nrho yog sib npaug li ntawm 5 lub sij hawm tas mus lilossis 5T.
Lub sijhawm twg yog ntau dua?
rau lub caij nplooj zeeg teev V(t) sib npaug rau 0.37Vmax, txhais tau tias lub sijhawm tas mus li yog lub sijhawm dhau mus tom qab nws poob rau 37% ntawm V max. Qhov loj dua lub sij hawm tas mus li yog, qeeb qhov nce lossis poob ntawm lub peev xwm ntawm neuron.
pes tsawg feem pua yog lub sijhawm tas li?
RC Lub Sijhawm tsis tu ncua. Lub sij hawm yuav tsum tau them tus capacitor mus rau 63 feem pua (tiag tiag 63.2 feem pua) ntawm tag nrho cov nqi los yog kom tso tawm nws mus rau 37 feem pua (ua tau 36.8 feem pua) ntawm nws thawj voltage yog hu ua TIMECONSTANT (TC) ntawm Circuit Court. Tus nqi thiab tawm nkhaus ntawm lub capacitor muaj nyob rau hauv daim duab 3-11.
