问题 图示电路中U= 10V,电阻均为100Ω,则电路中的电流I应为下列哪项数值?()
选项 A.(1/14) B.(1/7) C. 14 D. 7
答案 A
解析 解:由对称电路可知: Rcq=2(100//100) + [(100//100)//(50 + 100 + 50)] =140Ω

相关内容:电路,电阻,电流,数值

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.
