(UO-Ui2)/R2=(Ui2-Ui1)/R1
(UO-Ui2)=(Ui2-Ui1)R2/R1
(UO-Ui2)/R2=(Ui2-Ui1)/R1
(UO-Ui2)=(Ui2-Ui1)R2/R1
UO=R2/R1(Ui2-Ui1)+Ui2
(UO-Ui2)=(Ui2-Ui1)R2/R1
(UO-Ui2)/R2=(Ui2-Ui1)/R1
(UO-Ui2)=(Ui2-Ui1)R2/R1
UO=R2/R1(Ui2-Ui1)+Ui2
追答
前面二两行重复了,取消。
(UO-Ui2)/R2=(Ui2-Ui1)/R1
(UO-Ui2)=(Ui2-Ui1)R2/R1
UO=R2/R1(Ui2-Ui1)+Ui2
Ui2=0时:
Uo=-Ui1(R2/R1)
Ui1=0时:
Uo=Ui2[1+(R2/R1)]
