电路如图所示,已知US=3V,IS=2A,则I=()A。http://image.zhihuishu.com/zhs/onlineexam/ueditor/201811/c7e41c936dd14063a9d7f0b7f7979da3.png
举一反三
- 电路如图所示,已知 Uab=10V,Iab=2A, 则Iba =( )A。http://image.zhihuishu.com/zhs/onlineexam/ueditor/201811/3e92b7fefd934290bd4436e2e6e6c694.png
- 图7所示电路,若已知电流I=1A ,则 Uab= ( )http://image.zhihuishu.com/zhs/onlineexam/ueditor/201804/51368429af7741c8a3acecb0e789389d.png
- 如图5所示电路中,Is=0时,I=2A,则当Is=8时,I=( )。http://image.zhihuishu.com/zhs/onlineexam/ueditor/201903/83ffe24312a04f02a0d192228be2ca97.png
- 如图所示的电路中,已知ui1=1V,ui2=2V,则uo=( )V。http://image.zhihuishu.com/zhs/onlineexam/ueditor/201811/e726404aacc0459c9038e086018b6ca0.png
- 下图所示机构自由度计算,( )是正确的。 A: mg src="http://p.ananas.chaoxing.com/star3/origin/cb07ca0fb12be985c301490389c1e187.jpg" B: F=3×7 –(2×9 + 2 – 2)– 2 = 1 C: F=3×7 –(2×9+ 2– 0)– 0 = 1 D: F=3×7 –(2×8+ 2 – 0)– 2 = 1 E: F=3×5 –(2×6+ 2– 0)– 0 = 1
