What is the electrochemical equivalent of the term "current"?

The term "current" in an electrochemical context refers specifically to the flow of electrical charge. In an electric circuit, current is defined as the rate at which electric charge flows past a point in the circuit, typically measured in amperes (A). This flow of charge is crucial for electrochemical processes, as it enables the movement of ions in solutions and facilitates various reactions at the electrodes.

Voltage represents the electric potential difference that drives the current, while resistance quantifies how much the flow of current is hindered by a material. Charge refers to the property of matter that experiences a force in an electromagnetic field, but does not convey the dynamic aspect of how that charge moves within a circuit. In contrast, the flow of electrical charge captures the essence of current, highlighting its nature as a dynamic and continual process essential for electrochemical reactions.
