Galvanic (Voltaic) and Electrolytic Cells - Chemistry

This video explains the difference between galvanic (voltaic) and electrolytic cells, including a diagram, anode vs cathode (where oxidation and reduction occur), and worked example question. In galvanic cells, the redox reaction is thermodynamically favoured and can be used to produce electricity, and in electrolytic cells, an external power source is used to drive the thermodynamically unfavoured redox reaction.
