A paper was presented at two conferences in Brazil last year saying that there is now a definitive criterion for cathodic protection that makes it possible to calculate if corrosion has stopped. The present criteria cannot be computerised as the half-cell is not used as a reference electrode in eit

can anyone send me the link of different electrical standards used in industries?

The image below shows a part I am trying to create, it is in effect a square internal circlip. I have envisaged this as 2 square bars held apart by 2 wire form springs. I've drawn these springs with a simple loop but I'm wondering if there is a better shape to ensure that the arms of the springs rem
