Understanding Electric Potential Difference

The video tutorial explains the concept of electric potential difference, which is the work needed to move a charge between two points. It highlights that charges flow due to differences in potential and that this difference is measured in volts. The tutorial also covers the typical voltage in household outlets, which is 120 volts, and notes that larger appliances may require 220 volts.
