  2. Twin-lead - Wikipedia

    en.wikipedia.org/wiki/Twin-lead

    The name twin lead is most often used to refer specifically to 300 Ω (Ohm) ribbon cable, the most common type, but on occasion, twin lead is used to refer to any type of parallel wire line. Parallel wire line is available with several different values of characteristic impedance such as twin lead ribbon cable (300 Ω), window line (300 Ω, 350 ...

  3. Characteristic impedance - Wikipedia

    en.wikipedia.org/wiki/Characteristic_impedance

    At a distance x into the line, there is current phasor I(x) traveling through each wire, and there is a voltage difference phasor V(x) between the wires (bottom voltage minus top voltage). If Z 0 {\displaystyle Z_{0}} is the characteristic impedance of the line, then V ( x ) / I ( x ) = Z 0 {\displaystyle V(x)/I(x)=Z_{0}} for a wave moving ...

  4. Bifilar coil - Wikipedia

    en.wikipedia.org/wiki/Bifilar_coil

    A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire for transformers. Wire can be purchased in bifilar form, usually as different colored ...

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    Parallel resistance is illustrated by the circulatory system. Each organ is supplied by an artery that branches off the aorta. The total resistance of this parallel arrangement is expressed by the following equation: 1/R total = 1/R a + 1/R b + ... + 1/R n. R a, R b, and R n are the resistances of the renal, hepatic, and other arteries ...

  6. Inductance - Wikipedia

    en.wikipedia.org/wiki/Inductance

    A coiled wire has a higher inductance than a straight wire of the same length, because the magnetic field lines pass through the circuit multiple times, it has multiple flux linkages. The inductance is proportional to the square of the number of turns in the coil, assuming full flux linkage.

  7. Space cloth - Wikipedia

    en.wikipedia.org/wiki/Space_cloth

    Transmission line composed of two parallel wires terminated by space cloth. The characteristic impedance of a two parallel wire transmission line is given by [6] [c] = ⁡, where d is the diameter of the wire and D is the center to center separation between the wires.

  8. Parallel communication - Wikipedia

    en.wikipedia.org/wiki/Parallel_communication

    Parallel versus serial communication In data transmission , parallel communication is a method of conveying multiple binary digits ( bits ) simultaneously using multiple conductors. This contrasts with serial communication , which conveys only a single bit at a time; this distinction is one way of characterizing a communications link .

  9. Electrical length - Wikipedia

    en.wikipedia.org/wiki/Electrical_length

    In electrical engineering, electrical length is a dimensionless parameter equal to the physical length of an electrical conductor such as a cable or wire, divided by the wavelength of alternating current at a given frequency traveling through the conductor. [1] [2] [3] In other words, it is the length of the conductor measured in wavelengths.
