Q

Why are large cable sizes often formed as individual conductors comprised of several smaller strands?

🔍 Key Concepts

• Stranded vs. solid conductors in large cable sizes • How flexibility and mechanical handling change with cable construction • How skin effect behaves in AC circuits and what it affects

💭 Think About

• Think about what happens when you try to bend a very thick, solid wire compared to many smaller wires bundled together. • Consider which cable property skin effect actually changes: resistance, weight, or flexibility? • Ask yourself: for a fixed overall wire size (same copper cross‑section), does stranding significantly change the basic DC resistance?

✅ Before You Answer

• Identify which choice directly mentions flexibility/handling and whether that is true for stranded conductors. • Decide whether skin effect tends to increase or decrease current crowding at the surface in large conductors and how stranding might influence that. • Eliminate any options that confuse mechanical properties (weight, number of supports) with electrical properties (resistance, AC behavior).
