[wireties]

FYI - When electricity flows through a wire, it mostly flows on the surface of the wire, not through the middle. This effect is more pronounced on high frequency AC than it is on DC or low frequency AC. This means that a "wire" of a given size that made up of many smaller strands can carry more power than a solid wire - simply because the stranded wire has more surface area. Plus flexibilty is key on our robots and all the termination mechanisms we are given work best on stranded wire.

So... my professional opinion is there are no compelling reasons to use solid-core wire on a FRC robot (even if it was donated).
