下面是小红和小文同学在“探究串联电路中的电压关系”时所设计的实验报告．实验目的：通过实验探究，理解串联电路中总电压与各部分电路电压之间的关系．器材：电源、两个相同的小灯泡L₁、L₂、一个开关、导线若干条、一只电压表．

实验步骤：

（1）设计实验电路图；

（2）按照所设计的电路图连接好电路；

（3）将电压表并联在灯L₁两端，经检查连接无误后，闭合开关，测出灯L₁两端的电压U₁为3V；

（4）再将电压表改接在灯L₂两端，经检查连接无误后，闭合开关，测出灯L₂两端的电压U₂为3V．

得出结论：串联电路中，各部分电路电压相等，即U₁=U₂ 小红和小文接下来进行了交流与评估，她们认为：

①实验开始前，匆忙忘记了画出实验电路图，请你补画在虚线框内．

②在实验步骤中，缺少了一个重要的探究步骤，请你替她们补上：_________．　

③请你为她们设计一个正确实验时所需记录数据的表格．

④请你对小红和小文的实验过程中存在的问题进行评估，并指出改进措施．
