Answer to Question #72060 in Mechanical Engineering for queue

Question

I usually Mount the sample (Working Electrode) for potentiodynamics polarization studies to obtain Tafel plots. What is the significance of height of sample which is used for three electrode cell?
Because I recently used sample with height of 3cm and I could not obtain the Tafel plot, the software just gave random scattered points.
I again prepared the same sample by cutting it and decreasing its height to almost 1cm and the results obtained were fine.
So, please tell the significance of height of the working electrode and why does it only gave the scattered data??
