在图示电路中，电压 UAB 应为http://image.zhihuishu.com/zhs/onlineexam/ueditor/201803/0532e9a652e74b798038be26aa5d4f2c.png
举一反三
- 在图示电路中，已知 US = 12 V, IS = 2 A。A、B 两点间的电压UAB 为http://image.zhihuishu.com/zhs/onlineexam/ueditor/201803/fc771cadc4804250b1dc3e80378bcdb3.png
- 在图示电路中，已知：IS=5A，当IS，US共同作用时，UAB=4V。那么当电压源US单独作用时，电压UAB应为http://image.zhihuishu.com/zhs/onlineexam/ueditor/201803/af2fa2180c7a479a8100fce81ad48209.png
- 图示电路中A点电位VA为http://image.zhihuishu.com/zhs/onlineexam/ueditor/201803/0d56751fd15748d29f6150e525165170.png
- 图示电路中，理想电压源发出的功率 P 为http://image.zhihuishu.com/zhs/onlineexam/ueditor/201803/c04b03f213394b0ca8c9f98372847980.png
- 在图示电路中，B点的电位VB为http://image.zhihuishu.com/zhs/onlineexam/ueditor/201803/0de1efa422f14410b078cf364c59cdc7.png
