Speaker wire - another fine theory
(Richard D Pierce) wrote in message
Double dude, go back to reading class, that's NOT what we are
talking about at all.
I must confess, I'm *guilty as charged*.I didn't read the message
carefully enough. (However, my statement was technically correct. The
inductance of a single straight wire does decrease as the wire
diameter increases.)
However *you* are also guilty of not reading carefully. The subject
was a transmission line (speaker cable) *not a loop of copper wire*. A
transmission line is two conductors in parrallel, with a termination
at the end. The termination can be any impedance. *Only* if the
termination is a short, will the speaker cable have the
characteristics of a wire 'loop'. If the termination is an 'open', the
line (at audio frequencies) will look like a capacitor. If the
terminated is a resistor (of the correct impedance), the line will
look resistive to the amplifier (not inductive or capacitive).
As the spacing between the two parallel conductors increases, the
capacitance between the two conductors decreases, but the inductance
of each conductor *remains the same*. Only if the termination is a
short, does the loop inductance increase.
