<p>Oh, I just looked up the specs of the capacitance range on a cheap AN8008 multimeter I have - On the 9.999nF range the resolution of 0.001nF, 5% +/-20 counts. That should be able to measure around what you need, assuming cables are within the ~100pF/m range.</p>
<p>You are more than welcome to borrow that if you want, or pop over and try to measure a few cables.</p>
<p>Can try it tonight and report back...</p>

<div dir="auto">Hello all
<div dir="auto"> </div>
<div dir="auto">I am trying to support my 14yo boy with his homework but am a bit out of my depth. He is aiming to demonstrate understanding of the scientific method. To do this he wants to make a comparison of the electrical properties of different brands of audio cables. His hypothesis is that there is no difference between 'audiophile' cables vs cheapies.</div>

<div dir="auto">I under that folks talk about capacitance being a variable. I'm told that this will be very small in any cable and potentially difficult to read (in the tens of pF range).</div>
<div dir="auto"> </div>
<div dir="auto">Does anyone out there have the equipment necessary to do this? If so, could we bring some cables to you for testing?</div>
