In the theory of induced electrical polarization, a dilution factor, B, is a measure of the sensitivity of the apparent resistivity of an object to changes in the apparent resistivities of other objects. Intuitively, one would expect B to exhibit two characteristics: When measured far away from an object, B should be small. And, when measured inside an object, away from all interfaces, B should be close to unity. Surprisingly, the second expectation is not always met. The actual behavior becomes clear upon consideration of the action of charges within the object.
