Answer :

Difference between Solid Conductor and Stranded Conductor
Solid Conductor:
It consists of single piece of metal wire. It is cheap for manufacturing.Skin effect is higher in solid conductors as at higher frequencies current flow on the surface of the conductors results in the increase in the effective resistance. The main disadvantage of the solid wire is its more rigid property. It cannot be bent easily
Stranded Conductors:
Stranded wire consists of sub conductors touch each other. It is costlier to manufacture compared to solid wire. For the given current carrying capacity the size of the stranded conductor is large compared to solid wire. Different elements of strands can be wound together to get the transmission line of desired property (eg: ACSR conductor contains Aluminum and Steel stands wound together). Proximity and skin effect is reduced using stranded conductors.

Which wire can carry a higher current stranded wire or solid wire?

Description : Which wire can carry a higher current stranded wire or solid wire?

Last Answer : From the formula R=PL/A resistance rise with the fall of surface area ,inverse proportion relation between Resistance and Area ,so stranded wire has more area that a solid wire so more area less resistance. Less resistance/less electron flow opposition,more electron flow (current)
