What defines a solid conductor?

What defines a solid conductor?

• A. Made of a single solid strand of metal
• B. Made of multiple strands twisted together
• C. Contains an embedded rectifier
• D. Has a hollow core

Answer: (A)

A solid conductor is defined by being a single, continuous piece of metal that provides a solid cross-section for current to flow through. This makes it rigid and easy to terminate in fixed installations. It’s what distinguishes it from stranded conductors, which are made of many small wires twisted together and are more flexible. The other options describe features not about the basic construction of the conductor: a rectifier is an electronic component, not part of the conductor’s physical form; and a hollow core would mean the cross-section isn’t solid metal, so it isn’t a solid conductor.
