What best defines a solid conductor?

• A. One solid wire - one piece of metal
• B. Many strands twisted together
• C. A conductor with a hollow core
• D. Any conductor less than 10 AWG

Answer: (A)

A solid conductor is a single, continuous piece of metal with no strands. This makes it stiff and its shape predictable, which is why it’s used in fixed wiring and through conduits. In contrast, a conductor built from many strands twisted together is called stranded and is much more flexible, good for cables that need to bend. A conductor with a hollow core isn’t solid at all—it’s a hollow tube, not a solid wire. And gauge alone doesn’t define solid versus stranded; wires of various gauges can be either solid or stranded.
