This book addresses the topic of instrumentation and electrical measurements in direct and alternating current circuits.

In the first part, which relates to instrumentation, a basic number of electrical instruments is analyzed in terms of construction, corresponding symbolism, operation, and usage.

The second part describes the method of conducting electrical measurements of various electrical quantities encountered by the electrical technician-electronics engineer in direct current circuits.

The third part also describes the method of conducting electrical measurements of various electrical quantities encountered by the electrical technician-electronics engineer in single-phase and three-phase alternating current circuits.

The various chapters of the book include all the necessary knowledge of electrical engineering that the student must know, so that in conjunction with the questions at the end of each section and the model solutions provided at the end of the book, they can acquire both the theoretical and practical aspects of electrical measurements.
