In answer to a question that RUclips doesn't seem to want to put in the comments: Question: In Example 3.2.1, I get current density i = 0.00086 A/m^2. Where may the factor of 1000 have come from. Answer: almost certainly from the atomic weight, which for practical purposes has units of grams / mole (however it is conventionally written as a dimensionless number), whereas the density is in kg/m^3. I flag this up in the live lecture if I have time.
thank you very much for these videos, these would certainly help me go through the corrosion class
