Yes, I am talking DC.Where do the electrons flow in a bundle? I mean, if the sum of the resistance of the individual wires is higher than the resistance of the bundled up wires, there has to be some other path they take.
- In case of repeated flexing (eg in wires to an elevator), a single conductor will suffer stress, and fail. Many thin conductors do not get as stressed, and even if one strand breaks, the other surrounding strands can conduct current around the break.
does the oxydation of the copper Affect?
