SOLUTION

1. Stranded Conductors are widely used over solid conductors. Although there seems to be more expensive than a solid conductor but offers many advantages too, over the solid conductor.
2. The stranded conductor offers much surface area for the flow of current that results in the reduced diameter of the conductor for the same current carrying capacity.
3. As the Stranded conductor offers much surface area so the overall resistance of the conductor is lesser than the same size solid conductor.
4. Eddy’s current losses are very much lesser than the solid conductor.
5. Stranded conductors are very suitable for an external environment and reduce the risk of loose connection.
6. Stranded Conductors offer much flexibility hence have a longer life than the solid conductor.
