Which term describes a conductor that is solid and has no strands?

• A. Multistrand
• B. Solid Core
• C. Multiconductor
• D. Two-wire

Answer: (B)

A solid-core conductor is a single, solid piece of metal with no strands. This construction makes the wire stiff and less flexible, ideal for fixed wiring where repeated bending isn’t expected. Stranded conductors are built from many fine wires twisted together, which increases flexibility and fatigue resistance. The other terms describe different ideas: multistrand refers to many strands within the conductor, multiconductor means multiple conductors in a single cable, and two-wire describes the number of conductors in a circuit rather than the conductor’s internal construction. Therefore, the term for a conductor that is solid and has no strands is solid core.
