摘　　要：对用电压表测量RLC串联时元件电压计算问题提出质疑,通过实验测量得出不同的结论,分别从理论和实际方面进行分析与研究,提出合理的求解方法,并引发相应的教学思考。要科学地求解习题,必须重视命题规范,区分模型化的实际问题与具体的实际应用问题,同时注意转变教学观念,重视在教学中的理论联系实际。The problem of voltage calculation when measuring RLC series with voltmeter is questioned.Different conclusions are obtained through experimental measurement.Analysis and research are carried out from theoretical and practical aspects respectively.And the correct solution method is put forward and corresponding teaching thinking is triggered.In order to solve exercises scientifically,we must attach importance to the specification of propositions,distinguishing between modeled practical problems and concrete practical problems,and at the same time paying attention to changing teaching concepts and attaching importance to integrating theory with practice in teaching.
