摘要
基于LC串联电路存在"零电阻"状态的电路特性,利用标准电感线圈和自制液体电容器,设计了可以精确测量液体电容率的实验方法.利用该方法测量了蒸馏水以及不同体积分数乙醇溶液的电容率,测量结果与文献参考值的相对偏差在1%以内.
Based on the unique characteristic of series LCcircuit,a method was designed to measure the capacity of liquid materials,using a standard inductor and a cylinder capacitor.Using the above method,the capacity of distilled water and alcohol solution was measured.The relative error between the measured result and the reference value was less than 1%.
