The Tafel curve is widely used in electrochemistry, especially in the study of corrosion. Using the Tafel curve one can determine the corrosion potential

or open circuit potential. The coefficient of charge transfer

can also be determined as the slope of the Tafel curve. This Demonstration shows the current-potential curve on the left and the Tafel curve,
