ta có:
[TEX]C_12=4uF[/TEX]
[TEX]C_123=4+4=8uF[/TEX]
[TEX]C_45=4uF[/TEX]
[TEX]C_b=8/3 uF[/TEX]
->[TEX]Q_b=C.U=8/3.24=64uC[/TEX]
->[TEX]Q_4=Q_5=Q_123=64uC[/TEX]
[TEX]U_4=U_5=8V[/TEX]
->[TEX]U_123=24-16=8V[/TEX]
->[TEX]U_12=U_3=8V[/TEX]
nên [TEX]Q_3=C_3.U_3=4.8=32uC[/TEX]
[TEX]Q_12=Q_123-Q_3=64-32=32[/TEX]
-> [TEX]Q_1=Q_2=32uC[/TEX]
