My understanding is that electrons only actually travel (well, in so much as
electrons actually travel) along the diameter of a wire, not all the way
through it. (I don't recall why...) So a thick solid wire concucts much
less than a bunch of small stranded wires.

Question)

Quick question, though (especially since Larry is the high voltage
expert) - what's the deal w/stranded vs. solid wire? I've been using
14ga solid copper wire for the main (800mA or 1.5A) DC out, but
(IIRC) Larry recommends stranded. What's the reason for this? (And,
do I risk screwing things up by using solid?) (And, for that matter,
why is stranded used for all audio applications, from microphone
level to power amp speaker level?)
