Rate of Electrical Current Flow Through the Corrosion Cell

The presence of an electrolyte and a solution between two metals or electrodes is required for galvanic corrosion to occur. Some limitations of the calculation are non-customizable size and type of the electrode and resistivity of the solution.

𝐼 − Rate of electrical current flow through the corrosion cell (amps)
𝐸𝑐 − Potential of the cathode with respect to a reference electrode(V)
𝐸𝑎 − Potential of the anode with respect to the same reference electrode,V.
𝑅𝑡 −Total resistance to electrical current dlow through cell(ohms)
