The name inductivity, or dielectric capacity, or specific inductive capacity is given to the ratio between the capacities of two condensers of the same size and shape, one of them filled with the specified dielectric, and the other an air condenser. The inductive capacity of dry air at standard conditions is usually taken as the standard. Therefore, the measurement of the specific inductive capacity of any given dielectric resolves itself into the measurement of the capacity of a condenser with the given material as dielectric.
