The contact surfacentact spots set in. The sum of all these small contact areas makes up the .., which is much smaller than was formerly supposed. For example, the load-bearing contact area between a brush and a slip ring can be hundreds or thousands of times smaller than the polished area; the latter area we call the .., cf. §§ 1 and 4.

Introduction. A simplified summary of the theory of stationary electric contactsantitative character by means 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.

Bestimmung des optimalen Kapitaleinsatzes,ct area on the load cannot be given. But instructive formulas can be deduced for representative cases, just as in § 4 resistance formulas for particular cases were formed, which provide the possibility for fairly general computations.
