Solid Core or Multistrand?

[Diesel]

Well - is one better than the other?

What do the pro's prefer?

Cheers, Diesel

multicore, its more flexible

[Biggles]

No one uses solid core for automotive or motorcycle applications.
As Brock says,  multi is flexible.  I'd hate to thread single through a bike.  It would be easier to poke through a gap, but a horror on bends.
Apart from that IIRC, electrons flow along the surface of a conductor, and with a vastly higher surface area, the current will encounter less resistance on multi-core, hence heat up less and lose less voltage.

Multicore cable is far more resistant to vibration.  Solid core copper will work harden and break.

Forget solid core, you will probably have difficulty actually finding any I think, multi-core is the only real choice, for all the reasons stated above!

Biggles, Its my understanding that this Skineefect as its called only happens as very high RF frequencis (in the Gigahertz range)

Though Audiophiles will swear that it happens in their speaker/amplifier systems, thats why they use that gold plated oxy free mono linked copper chain molecular 10mm diameter speaker wires, at $100 a metre. But thats another story.

(Befor youy spend lost of dollars on speaker cable, look inside the speaker and see what sort of wire goes from the connectors to the speaker cone, its nothing special.)

Have you been asleep?  That was posted over 2 weeks ago.  It's disproven physics now we know more about Boson particles!

Dont believe everything you see/hear on GBig Bang Theory, except Penny of course..
