AC Voltage Calculation - Vrms Vmax Frequency

The video tutorial explains the nature of AC electricity, where voltage and current alternate directions due to a magnetic field in the generator. It describes how this results in a sine wave pattern, with voltage peaking at positive and negative values. The concept of root mean square (RMS) voltage is introduced, explaining how it is calculated and used in multimeters. The tutorial compares power outlets in different regions, highlighting differences in voltage and frequency. It concludes with a summary of peak voltage values in various electrical systems.
