分压电路工作原理分析方法的要点分析分压电路的关键点有以下两个。找出输入端。需要分析输入信号电压从哪里输入到分压电路中，具体的输入电流回路如何。电路识图中确定输入信号电流回路的方法：从信号电压的输入端出发，沿至少两个元器件（不一定非要是电阻器）到达地线。找出输出端，即输出电压取自于电路的哪个端点。分压电路输出的信号电压要送到下一级电路中，理论上分压电路的下一级电路输入端是分压电路的输出端，但是识图中这种方法的可操作性差，因为有时分析出下一级电路的输入端比较困难，所以可以采用更为简便的方法进行分析：找出分压电路中的所有元器件，从地线向上端分析，发现某元器件与分压电路之外的其他电路相连时，这一连接点便是分压电路的输出端，这一点的电压就是分压电路的输出电压。
