These chapters also explore the atomic theory of electric current and the electric circuit, conductors, and insulators. The subsequent chapter focuses on the chemistry of an electric cell, which is classified into two types, namely, the primary and secondary cells. This text also describes the principles, construction, types, and specifications of direct current machines. A chapter emphasizes the storage of energy for short periods in a capacitor, along with a brief discussion of its theory and construction. Other chapters are devoted to alternating-current systems. The remaining chapters cover the commonly used electrical measuring instruments in electrical installation work. This book is an invaluable source for electricians.
