Abstract
The book is dedicated to the school physics experiments from the area of alternating currents and to their applications. The first part of the book summarizes the basic knowledge associated with the description of harmonic quantities.
This is followed by introduction to measurements using a simple oscilloscope, an experimental investigation of electrical power in an AC circuit and examining the concept of RMS current and voltage. The second part of the book is devoted to applications of alternating currents around us.
Theoretically and experimentally analyzes the basic issues related to the functioning and safety of electric distribution systems at home or in a school laboratory. Also presents possibilities for safe demonstration of their principles in the teaching of physics.
