Have you ever wondered how a battery works? It's redox chemistry! A redox reaction is split up into half cells, and you have an oxidation at the anode producing electrons to drive the reduction at the cathode. This flow of electrons can do work, and that's an electric current. This is called a galvanic cell. Of course modern batteries are very complicated, but that's the long and short of it. Let's construct a few different galvanic cells from a few different pairings of half cells, measure the current produced, and see how well it matches up with theoretical calculations!
