Introduction to Potential Dividers and Their Applications

The video tutorial explains potential dividers, which split a fixed potential difference across resistors. It covers calculating potential differences in circuits, generalizing the concept with resistors R1 and R2, and introduces variable potential dividers. The tutorial also discusses using special resistors like thermistors in potential dividers to control devices based on temperature changes.
