A Möbius resistor is an
electrical component
An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not ...

conductive
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electric current) in one or more directions. Materials made of metal are common electrical conductors. Electric current is gener ...
surfaces separated by a
dielectric
In electromagnetism, a dielectric (or dielectric medium) is an electrical insulator that can be polarised by an applied electric field. When a dielectric material is placed in an electric field, electric charges do not flow through the mate ...
material, twisted 180° and connected to form a
Möbius strip
In mathematics, a Möbius strip, Möbius band, or Möbius loop is a surface that can be formed by attaching the ends of a strip of paper together with a half-twist. As a mathematical object, it was discovered by Johann Benedict Listing and Augu ...

, once the Möbius resistor is connected up in this way it effectively has only one side and one continuous surface.
Its connectors are attached at the same point on the circumference but on opposite surfaces.
It provides a
resistor
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active el ...

self-inductance
Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The flow of electric current creates a magnetic field around the conductor. The field strength depends on the magnitude of th ...
, meaning that it can resist the flow of electricity in a more frequency-independent manner.
Transmission line
Due to a symmetrical construction, the voltage between the conductive surfaces of the Möbius resistor in the point equidistant to the feed point is exactly zero. This means that a short circuit placed at this point doesn't influence the characteristics of the device. Thus, the Möbius resistor can be thought of as two shorted lossy (resistive)
transmission line
In electrical engineering, a transmission line is a specialized cable or other structure designed to conduct electromagnetic waves in a contained manner. The term applies when the conductors are long enough that the wave nature of the transmis ...
segments, connected in parallel at the resistor's feed point.
