    Do you know the formula for the resistance of the winding wire of a copper model? :D N2E 180 or DN2E 200 or ordinary enamel wire depending on its diameter and length.
    I think this is the wire parameter, which is the number of ohms per meter of length.
    The pattern I am looking for is needed to select the appropriate wire diameter so that the specified number of turns has the assumed resistance, in this case it is a loudspeaker coil.

    it is best to "unwind" the given resistance, and then move on to ...

    or unfold the meter and measure carefully!

    R = ro * l / s

    ro = 0.017 ohm * mm ^ 2 / m

    l - wire length

    s - cross-sectional area

    Capricorn not better a meter, e.g. 10 or 100m, and the measurement error, resistance of the meter leads, etc.? Well, but preferably from the pattern.

    everyone does their own thing, and it's best to just buy a ready-made coil!

    In the Elfy catalog, which is somewhere on the electrode here, there is a table of wire resistance diameters and other parameters

    Hello

    And the tables are here, and if you want, look for a program called "CPW" by mate_ok, such a small but useful application that will help you with air coils, if you do not find it, give it an e-mail and send it to you ...

    Regards!

Topic summary

The discussion centers on calculating the resistance of copper winding wire, specifically for models N2E 180 and DN2E 200, as well as ordinary enamel wire. The main formula provided for resistance (R) is R = ρ * l / s, where ρ is the resistivity (0.017 ohm * mm²/m), l is the wire length, and s is the cross-sectional area. Participants suggest measuring longer lengths for accuracy and refer to resources like the Elfy catalog for wire resistance tables. Additionally, a software tool called "CPW" is mentioned as a useful application for designing air coils.
