about 330m (1,100 feet) of cable. Audio cable is available in three ra most flexible and snake cable, has about 30-34 pf per foot. Low-capacitance cable has about 20 pf per foot and is more expensive. Special cable constructions optimized to reduce noise pickup (star-quad and some double-shielded cables) have 46-56pF per foot.

All those cables have a length of 3-6 feet and their capacitance measured from 300 to 600 pF. The best generic cable had a capacitance of 328 pF per meter, which is too high for my tastes. Generic RCA cable (328 pF per meter): After that, I turned my attention to some of the premium cables that I had lying around.
How to measure speaker cable inductance and capacitance?

Use a piece of cable -much- shorter than a wavelength of this frequency. Measure the capacitance of an open circuited piece Measure the inductance of a short circuted piece. divide by the length of the piece to get cap per unit length and inductance per unit length. characteristic impedance is sqrt(l/c) propagation constant is sqrt(l*c)

Typically cables run around 20~30 pF/foot (RG-6, commonly used for TV and audio interconnects, is around 21 pF/ft) so you are measuring in the very lowest part of the meter's range. These meters are mainly to check large power supply decoupling capacitors and larger interstage coupling capacitors.

Cspec= Capacitance in pF per m cable length C= Cspec× d 1 pF (Picofarad) = 10−12F (Farad) Formula for the lengthof the cable dand a given cutoff frequency fc: If you want to know how long the cable can be and permit a level attenuation of only 1 dB, you need to enter the double value of the cutoff frequency.
Audio cables capacitance question - Steve Hoffman …

While there is a relative capacitance to every connector, it is extremely small, and is generally not included as a specification. The more meaningful capacitance measurement would exist between the shield and inner conductor.... Even a connector with high capacitance (let's say, 50pf/ft), would have a short 2” length, and only add 8.33pf.

In the absence of a parasitic capacitance, a typical way to accurately measure a capacitance is make a half bridge circuit or potential divider. This allows the determination of an unknown capacitance by comparing it to a high precision calibrated capacitor. If C ref is known, it is trivial to determine C x because C x /C ref =V 1 /V.

Measuring Low Level Interconnects (RCA cables / patch cords)

The cable capacitance is responsible for the height of the square wave, but some other factor causes the rolled off shape. Note that this is only a 2 kHz test, so that rolled off portion is right smack dab in the middle of the audio band, contrary to many explanations for cable sound that only come into play at RF frequencies.
Calculation of Cable Capacitance - Electrical Concepts

C = Q / (Q / 2πξ)log (D/d) = 2πξ / log (D/d) = 2π ξ0ξr / log (D/d) Farad But the above capacitance is for cable of unit length. Cable Capacitance for axial length L is C = 2πL ξ0ξr / log (D/d) Farad From the above expression, we observe that cable capacitance depends on the diameter of conductor as well as earthed sheath.
