Möbius resistance

from Wikipedia, the free encyclopedia
Basic structure of a Möbius resistor

A Möbius resistor is a type of electrical resistor that ideally has no inductance . It has the shape of a electrically coated Möbius strip and was developed in 1966 by Richard L. Davis .

In the case of the Möbius resistor, the electrical current flows in opposite directions on the electrically conductive coating of the Möbius strip, as shown in the adjacent sketch. Due to the opposing current flow and the small thickness of the tape, the magnetic flow due to the current flow is compensated, so that the inductance of the arrangement is almost zero.

Other electrical resistances have a greater inductance, which is dependent, among other things, on the shape and the material. This property can be undesirable in certain applications, such as high-frequency technology .

The Möbius resistor and other low-inductance designs are used in the field of high-frequency technology and as shunt resistors with low inductance for measuring pulse currents.

Möbius resistors are of little practical importance.
