Abstract

Abstract: To overcome the shortcomings of the measurement procedure used for the Millikan oil-drop experiment course, this paper suggests a measurement reduction method based on simplification of the conventional formula. In this method, only the voltage and the fall time are required to be recorded. This method can also simplify the analysis and the measurement error of the experiment and give proper parameter intervals, which results in a small measurement error. A solution is conducted to calculate the value of the elementary charge, and this solution verifies the measurement reduction method.
