Differences between Direct and Alternating Potential Difference

The video tutorial explains the differences between direct and alternating currents. Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically. The video uses graphs to illustrate these concepts, showing how potential difference behaves over time for each type of current. It also covers the calculation of frequency and peak potential difference in AC, using the UK standard of 230 volts and 50 Hertz as examples. The tutorial concludes by explaining how these concepts apply to real-world applications like batteries and mains electricity.
