Which type of wire is characterized as the least flexible form of conductor?

• A. Stranded wire
• B. Solid wire
• C. Flexible wire
• D. Ribbon wire

Answer: (B)

Solid wire is characterized as the least flexible form of conductor due to its single, continuous strand of metal. This structure provides good conductivity and mechanical strength, making it ideal for certain applications. However, it lacks the ability to bend or flex easily like other types of wire, such as stranded wire, which is composed of multiple smaller strands twisted together. The design of stranded wire allows for greater flexibility and ease of handling, while flexible wire is specifically designed to bend and move without breaking. Ribbon wire, with its flat design, also provides more flexibility than solid wire. Therefore, solid wire’s rigidity is what defines it as the least flexible option among the choices.
