Modern developments in electrical standards and measurements

Abstract

In order to provide a suitable background for this subject, a brief account of some of the salient features of its history is necessary (Silsbee 1949). Although electrostatics is an ancient science, electromagnetism and hence electrical engineering was born in the year 1800, when Volta first produced a steady flow of electric current by means of the voltaic pile. In 1827 Ohm's law was enunciated, and then in 1831 Gauss and later Kohlrausch and Weber made magnetic and electrical measurements in terms of fundamental units.
