Solid and stranded wires see frequent use in electrical equipment, such as cable assemblies and wire harnesses. Solid wires consist of a solid core, whereas stranded wire consists of several thinner wires twisted into a bundle.

Is solid or stranded wire better?

In general, solid cables are better electrical conductors and provide superior, stable electrical characteristics over a wider range of frequencies. They are also considered more rugged and less likely affected by vibration or susceptible to corrosion since they have less surface area than stranded conductors.

Does solid or stranded wire carry more current?

Because of its thickness, solid wire has a decreased surface area that reduces dissipation. Because of the given thickness of stranded wire, i.e., it's thinner, there are more air gaps and a greater surface area in the individual strands of wire. Therefore, it carries less current than similar solid wires can.
