Understanding AC Voltage and Frequency

This video tutorial explains how to measure the frequency of alternating current using a multimeter. It begins with an introduction to the concept of frequency, measured in hertz, and its significance in alternating current. The video highlights the standard frequency in North America (60 Hz) compared to other regions (50 Hz). The tutorial then provides a step-by-step guide on using a multimeter to measure voltage and frequency, demonstrating the process with a power outlet. The video concludes with a summary and a call to action for viewers to like, share, and subscribe.
