Introduction. A simplified summary of the theory of stationary electric contactseans of some calculations, based upon an artificial model of the current flow lines which highly simplifies the treatment. In the later paragraphs the same model is used for the calculation of particular problems. Some of the concepts are defined solely in this introduction.

The inductance of a current constriction. Skin effect same radius, ., as the cylinders. We imagine a radial current to flow out through this sphere from . to .. In the surrounding body the lines of flow are assumed to be parallel to the axis of the cylinders as in Fig. (10.01).

The relation between contact load and resistance, particularly at moderate and high loadween isotropic materials, the contact surface is circular (elliptic between crossed rods of different diameters): and if its linear dimensions are less than 1/20 the dimensions of the contact members, the constriction is long and its resistance can be calculated according to Eq. (4.14).

Contact resistance on freshly cleaned rods in air at very small contact loadss were washed with soap and water and finally with alcohol. Sometimes they were also scraped with a clean tool, but there always was sufficient time to allow a deposit of the normal (chemisorbed) oxygen layers on silver. Without the film (perfectly clean) contacts would yield a conductance at . = 10. N several times larger than was observed.
