2、图3.11示电路已达稳态,当t=0时开关闭合,则初始值[img=44x24]180301aae36038a.jpg[/img]为 A。[img=456x250]180301aaed48a13.jpg[/img]图3.11
举一反三
- 图电路换路前已达稳态,在t=0时断开开关S,则该电路( )[img=200x114]17a3d9bd6d65995.png[/img]
- 图示电路开关原来闭合,且电路已达稳态。t=0是开关断开,则t>0时的电感电流等于[img=1596x1141]1802d0ee208af0e.jpg[/img] A: [img=85x43]1802d0ee2b3d0a6.png[/img] B: [img=101x43]1802d0ee3425a57.png[/img] C: [img=81x43]1802d0ee3d48207.png[/img] D: [img=101x43]1802d0ee460115a.png[/img]
- 在图示电路中,开关S在t=0瞬间闭合,当t = ∞时,电路的稳态电流 [img=45x44]17da5a9edfeef43.png[/img] =( )A。[img=254x139]17da5a9ecf96785.png[/img]
- 开关打开前,如图所示电路已达稳态,t=0时开关打开,则电容电压的初始值uC(0+)= V。[img=834x318]17de87ade94e7f3.png[/img]
- 电路如图所示,换路前电路处于稳态,在t=0时开关S闭合,当t = ∞时,电路的稳态电流[img=39x24]17e0c47283adcb2.jpg[/img]为( )A。[img=258x170]17e0c472904e7d0.jpg[/img]
