Cathodic protection effectively protects underground or submerged metallic structures through the use of a negative charge applied by an external source to the structure. The potential to which the structure must be polarized needs to be taken into account for different soil resistivities. This potential determines the degree to which the corrosion rate is reduced. It should be noted that the critical potential for cathodic protection of galvanized steel, stainless steel, copper and Aluminum is different from carbon steel.
