hello,
I want to calculate my corrosion current density. Therefore I need to draw tangets to a certain point on my graph. How can I do this?

Hello,

Would you please make further interpretation on the terminology 'corrosion current density' and 'tangets' with illustration or example?


Best regards!

In order to answer my question it is not that important to know what Corrosion current density means. It is just a characteristic dimension of an electrochemical system. A tangent is a linear slope that has only one common point with a graph.
