When using accelerometers with long cables, you must be careful that the cables do not attenuate the signals at high frequencies. Engineers at PCB Piezotronics point out that such attenuation may ...

Note: This article was originally published September 23rd, 2005 but we felt it was time for a little update based on some of the new products that surfaced to allegedly fix a non-existant problem.

Capacitance: 10 pF/ft DC Resistance: 0.003 ohms/ft Velocity Factor: 0.87 Inductance: 300 nHy/ft Note: Available as single cables or cable pairs in both I know what you are thinking - not another ...

At audio frequencies capacitance is not a factor at all for the cables your describe. These values are miniscule and are totally swamped by the input impedance of the audio amplifier.

You can use a multimeter with capacitance-measurement capability to measure the length of wire or cable to an open circuit. The capacitance of a pair of wires (or a wire to a shield) is directly ...
