Recreational Vehicle (RV) Technician Practice Test

What characteristic is associated with stranded wire?

1. Less flexibility

2. Higher resistance

3. Greater flexibility than solid wire

4. Increased durability

The correct answer is: Greater flexibility than solid wire

Stranded wire is characterized by its construction, which consists of multiple small strands of wire bundled together, rather than a single solid conductor. This design provides greater flexibility than solid wire, making it easier to bend and maneuver. This is particularly advantageous in applications where the wire needs to be routed through tight spaces or where frequent movement occurs, allowing for enhanced handling during installation and use. In contrast, solid wire, while more rigid and often used in applications requiring lower resistance and secure connections, does not have the same level of flexibility, which can limit its use in mobile environments, such as within RVs, where wire movement is common. The other characteristics, such as less flexibility, higher resistance, and increased durability, do not accurately describe stranded wire. Stranded wire is generally designed to be more flexible, not less, and although it can exhibit different resistance properties depending on the gauge and materials used, it is not inherently associated with higher resistance compared to solid wire in the same gauge. Lastly, while stranded wire can be durable, durability varies widely based on the wire's material and construction, making it an unreliable characteristic to attribute solely to stranded wire.
