问题 图示电路中,若时,电阻元件上的电压为0,则:
选项 A.电感元件断开了 B. —定有IL =I C.—定有iL =i D.电感元件被短路了
答案 B
解析 解:根据已知条件(电阻元件的电压为0)可知,电感支路与电容支路的电流大小相等,方向相反,可以写成IL =IC,或iL =-iC ,因此答案B正确。

错误啦!

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
