I personally believe you are the best lecturer for electrochemistry all over the world. This lecture was very very helpful for my thorough understanding of electrochemistry just at a glance. Gratitude from South Korea!

Dr.Kallol Mondal thank you for the best explanation of this topic
Note: You talked about the current all the time, but you re using a small letter I which might confused some people for thinking it to be the current density.

I holeheartdly appreciate your time to make us understand these concepts which would be abstract in your absence

[@ukaszjozwiak9468]

As simple as possible. It is understood from the first watching. I found a small nomenclature error at 38:52 the angle above the first "ra" is directed backward which is improper with the assumed nomenclature and should be forward. But it is an cosmetic error, does not matter. Thank You for that lecture and I will go to another. Greetings from Poland.
