Question 53Electricity & Electronics - 1st Asst/Chief

The correct answer is B) obtain the flexibility required for easy handling and reduces skin effect losses. Large cable sizes are often formed as individual conductors comprised of several smaller strands to provide the flexibility needed for easy handling and installation, as well as to reduce skin effect losses. Skin effect is an electrical phenomenon where alternating current tends to flow more on the outer surface of a conductor, leading to increased resistance. By using stranded conductors, the skin effect is reduced, improving the overall efficiency of the electrical system. The other options are incorrect: A) reducing the overall weight is not the primary reason, C) reducing resistance to current flow can be achieved but is not the main purpose, and D) reducing the number of supports is not directly related to the stranded conductor design.
