First question; I was measuring capacitance in various guitar pickup coils that have the same diameter of wire with an Extech LCR Meter, and it seemed to be that the more winds, the higher the inductance as expected, but I would get lower capacitance readings, too, both at 120 kHZ and 1k Hz. Could there actually less capacitance for more turns of wire, or is this an error in measurement?
Second question; in a normal capacitor, the dielectric has a big impact on the degree of capacitance, but I haven't found much information on how the different insulator materials between the coil windings would serve to act as a dielectric and alter the amount of parasitic capacitance. Is the effect of the insulator material negligible, or otherwise unimportant?
