The book "Visual electrotechnical task book" in 2 parts. Alexandrov V.A., Moscow

The Stargift collection contains a rare pre-revolutionary publication on applied electrical engineering. The task book was intended for obtaining electrical engineering skills.

Valentin Alexandrov is an engineer, the first popularizer of electrical knowledge among the masses. At the beginning of the 20th century, Alexandrov wrote a large number of educational books for electricians. All his manuals and reference books had a practical bias. It is noteworthy that during the period of the publication of the task book (1910s) in Russia, the training of electrical engineers was started. In many ways, it was thanks to Valentin Alexandrov that the foundation of the national school of technical electrical engineering was laid.

The publication consists of two parts:
1. Direct current and general laws of electrical engineering
2. Alternating current

The first part of the publication includes tasks on direct current and general laws of electrical engineering. The second part is designed to solve problems related to alternating current. It examines the basic properties of alternating current, single-phase and three-phase current, and ways to obtain it. A table of sines and cosines is provided.

Another feature of the task book is that each page has an appropriate place on the back for solving problems. In addition, each chapter is preceded by the necessary information and formulas.
