Lub peev xwm hloov pauv yog 9 microFarad.
2. Txheeb xyuas qhov them ntawm lub capacitor C2 yog tias qhov sib txawv ntawm qhov kawg A thiab B yog 9 Volts…
Kev Sib Tham
Nws yog paub :
Nug : Lub zog hluav taws xob ntawm lub capacitor C2 (Q2)
Jawb :
Qhov sib txawv uas muaj peev xwm ua tau :
Cov capacitors raug teeb tsa ua ke sib luag yog li qhov sib txawv ntawm A thiab B (VAB) = qhov sib txawv ntawm lub peev xwm hla lub capacitor C1 (V1) = qhov sib txawv ntawm lub peev xwm hla lub capacitor C2 (V2) = 9 Volts.
Lub zog hluav taws xob ntawm lub capacitor C2 :
Lub zog hluav taws xob ntawm lub capacitor C2 yog 270 microCoulomb.
3. Peb lub capacitors C1, C2 thiab C3 txuas ua ke, qhov twg txhua lub capacitor muaj peev xwm ntawm 4 microFarads, 2 microFarads, 3 microFarads. Peb lub capacitors raug them hluav taws xob txog li capacitor C2 muaj qhov sib txawv ntawm 4 Volts. Txheeb xyuas (a) lub zog hluav taws xob ntawm lub capacitor C1, C2 thiab C3 (b) Lub zog hluav taws xob ntawm lub capacitor hloov rau peb lub capacitors
Kev Sib Tham
Nws yog paub :
Nug : Lub zog hluav taws xob ntawm lub capacitor C3 (Q3)
Jawb :
(a) Lub zog hluav taws xob ntawm lub capacitor C3
Qhov sib txawv ntawm lub peev xwm hla capacitor C3 :
Cov capacitors txuas ua ke hauv parallel yog li qhov sib txawv ntawm cov capacitor C yog3 (V3) = qhov sib txawv ntawm lub peev xwm hla lub capacitor C2 (V2) = qhov sib txawv ntawm lub peev xwm hla lub capacitor C1 (V1) = qhov sib txawv ntawm lub peev xwm hloov pauv (V) = 4 Volts
Lub zog hluav taws xob ntawm lub capacitor C1:
Lub zog hluav taws xob ntawm lub capacitor C2:
Lub zog hluav taws xob ntawm lub capacitor C3:
(b) Lub zog hluav taws xob ntawm lub capacitor hloov rau peb lub capacitors
