Elementary charge measurement by water electrolysis

Abstract

This article presents an educational technique recommended for High School students or undergraduates on Physics or Chemistry education, which allows the measurement of the elementary charge through water electrolysis. The proposed experiment wraps material of easy attainment, the results have sufficient precision for the education purposes, and its realization promotes interdisciplinarity, since it wraps knowledge of different areas. In addition, this article presents results obtained by pupils in laboratory classrooms.
