Introduction to Cells and Batteries: Structure, Discharge, and Reactivity

This video provides an overview of cells and batteries. It explains the basic principles of chemical cells and how they work, as well as the structure and types of batteries, like dry cells. The video also discusses what happens when batteries are discharged and how the process can be reversed to recharge them. Additionally, the relationship between reactivity and voltage is explained, and how choosing different metals affects the voltage generated by a battery.
