Suppose that you have a 6.0V battery and you wish to apply a voltage of only 4.0V.Given an unlimited supply of 1.0Ω resistors,how could you connect them so as to make a "voltage divider" that produced a 4.0V output for a 6.0V input?
答案是connect three 1.0Ω resistors in series.
假设你有一个6.0 V电池和你想要申请一个电压只有4.0 给无限量供应的1.0Ω电阻器,你怎么能把它们连接起来形成一个“分压器”,制造了4.0 V输出为6.0 V输入?
（有道翻译，凑合着看吧）
答案是串联三个电阻
