注释在电路图中是十分重要的，电路图中所有的文字都可以归入注释—类。细看以上各图就会发现，在电路图的各个地方都有注释存在，它们被用来说明元件的型号、名称等等。
若不知电路的作用，可先分析电路的输入和输出信号之间的关系。如信号变化规律及它们之间的关系、相位问题是同相位，或反相位。电路和组成形式，是放大电路，振荡电路，脉冲电路，还是解调电路。电器修理、电路设计的工作人员都是要通过分析电路原理图，了解电器的功能和工作原理，才能得心应手开展工作的。作为从事此项工作的技术人员，首先要有过硬的基本功，要能对有技术参数的电路原理图进行总体了解，能进行划分功能模块，找出信号流向，确定元件作用。要学会维修电器设备和设计电路，就必须熟练掌握各单元电路的原理。会划分功能块，能按照不同的功能把整机电路的元件进行分组，让每个功能块形成一个具体功能的元件组合，如基本放大电路，开关电路，波形变换电路等。最简单的做法就是交换火线和零线的位置（如将两相插头转180度后再插入插座），这种方法一般很有效。因为有些用电器必须遵循“左零右火”的原则，插反后就会出现外壳漏电的现象。尤其是电脑及打印机等更要严格遵循这个原则。笔者就曾遇到了这种情况，插头插反后电脑主机和打印机都带了电，手不敢碰金属外壳，用电笔测试，氖泡很亮，用万用表测它与地的电压竟达到160多伏，交换火线和零线的位置后就一点电也不带了。
