Actually my Q1 is related to Q2. In Q1, since dielectrics are said to be not perfectly linear and can distort the signal (eventually sound I assume), I don’t know if the thickness of the dielectrics play a part in the degree of this nonlinearity (or sound distortion)?
Yes, it plays a part in how much the nonlinearity can affect the signal. The thinner the dielectric, the less effect any nonlinear polarization of the dielectric can have on the signal.
In the A2, it seems that because of increased (due to thinner dielectric) or decreased (thicker dielectric) capacitance, it brings different degree of distortion.
But the volume of the dielectric diminishes to a degree greater than the electric field increases which means that unless there is some highly unusual distortion behavior, the thinner dielectric will result in less distortion of the signal.
How about the thickness if the same dielectric is used for both the cables (thicker dielectric & thinner dielectric)?
That would be even more advantageous than a better but thicker insulation versus a worse but thinner dielectric.
In my last post, comparing Teflon to Teflon for both the thick and thin dielectric, the thick Teflon increased capacitance by a factor of 1.85 times what it would be with no dielectric and the thin Teflon increased capacitance by a factor of 1.25 times what it would be with no dielectric.
(p.s. sorry for the not-so-well organised questions)
No problem. We'll get it sorted out. :)
