Explore: Current Density

electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. The current density vector is

In electrochemistry, exchange current density is a parameter used in the Tafel equation, Butler–Volmer equation and other electrochemical kinetics expressions
