Electric Current: Crash Course Physics
So, electric current works like a river... kinda... Instead of flowing based on elevation, electric current works a little differently. But it's a good metaphor. In this episode of Crash Course Physics, Shini talks to us about electric...

Practice Problem: Galvanic Cells and Reduction Potential
We've learned about electrochemistry and electrochemical cells, especially galvanic or voltaic cells. And we learned about standard reduction potentials associated with a variety of substances. Given some data, can you calculate the cell...

Electrochemistry
How does a battery work? Now that you think about it, you have no idea, do you? Well take a gander! Turns out it's just redox chemistry.
