The term IR drop is a part of everyday vocabulary of cathodic protection personnel. The term consider the IR drop has been a source of controversy concerning the inclusion or exclusion of the IR drop component of pipe to soil potential measurements in the determination of effective cathodic protection. Throughout the controversy, the concept of IR drop has been assumed to be valid and this has been the assumption during past years. However, the case presented in this paper indicates that a technically valid Ohmic IR drop can exist only in the metallic portion of the cathodic protection system.
