举一反三
- 图示电路开关S原来处于闭合状态,当t=0时开关断开,则开关断开后的电容电流[img=16x21]180367caf29064e.png[/img]等于[img=2345x1100]180367cb0243584.jpg[/img] 未知类型:{'options': ['', '', '', ''], 'type': 102}
- 图示电路开关S原来处于闭合状态,当t=0时开关断开,则开关断开后的电感电压[img=19x17]180367cb27a3706.png[/img]等于[img=1705x1100]180367cb3577d75.jpg[/img][img=1705x1100]180367cb446a816.jpg[/img] A: [img=95x22]180367cb4d01994.png[/img] B: [img=85x22]180367cb5611aa1.png[/img] C: [img=81x22]180367cb5f62cd2.png[/img] D: [img=71x22]180367cb6807436.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]
