About the video
This lesson explains the process of converting alternating current (AC) to direct current (DC) using rectifiers. You’ll learn about the principles of half-wave and full-wave rectification, how pulsing DC is created, and the role of capacitors in smoothing out the current. The video breaks down the technical aspects of rectification, highlighting the differences between constant and pulsing DC, and how these concepts are applied in everyday devices like phone chargers. This comprehensive guide provides a clear understanding of how AC is transformed into usable DC power. To get started, go to the Lesson Content tab and click on the video.
