The dimensions of a bare stranded copper conductor can impact its?

The dimensions of a bare stranded copper conductor indeed influence various characteristics, making the correct choice inclusive of all aspects listed.

When considering weight, larger dimensions, such as a thicker or wider conductor, inherently add more mass, which can impact physical handling and structural support in installations.

Next, resistance is directly affected by the cross-sectional area of the conductor. According to Ohm's law and the principles of electrical conductivity, a thicker conductor will exhibit lower resistance due to its ability to carry more current more efficiently. This is rooted in the fact that resistance is inversely proportional to the cross-sectional area.

Moreover, flexibility is impacted by the stranding and dimensions of the conductor. Stranded conductors are generally designed to offer a balance between flexibility and conductivity, which means that as the size and number of strands change, so does the ability to bend and flex without breaking. A conductor with finer strands will typically be more flexible compared to one with fewer, thicker strands.

Therefore, all these properties—weight, resistance, and flexibility—are interrelated and vary based on the dimensions of the conductor, reinforcing the idea that the correct answer encompasses all the options listed.
