The article provides a theoretical analysis of various types of alternating current. These types of alternating current are used in industry, lighting networks, electrical and radio engineering, and also in computer networks. The following characteristics of alternating current are investigated: instantaneous, amplitude, average and effective (effective) values of current and voltage. The parameters of the average and effective (effective) values of sinusoidal, periodic, rectified, three-phase and pulsating current are studied. Various types of AC rectifiers, a phase-pulse regulator and a three-phase rectifier were considered as examples. Calculations were carried out to find the average and effective (effective) values of alternating currents and voltages generated using these devices and equipment. The principles of operation of magnetoelectric, electrodynamic and thermal measuring devices are analyzed.
