To determine the total DC loop resistance of the coaxial cable, you first need to understand how resistance scales with length. The given resistance is 1.34 ohms for every 1,000 feet of cable. Since the cable in question is 1,850 feet long, you can calculate the resistance for this specific length using a proportion.

First, set up the calculation by determining the resistance per foot:

1.34 ohms / 1,000 feet = 0.00134 ohms per foot.

Next, multiply this resistance per foot by the total length of the coaxial cable:

0.00134 ohms per foot * 1,850 feet = 2.479 ohms.

This value represents the total DC loop resistance for the specified length of coaxial cable. The significance of accurately determining total resistance lies in its impact on signal integrity and power loss in communication systems—critical factors for technicians and engineers working with such equipment.

Thus, the total DC loop resistance of 1,850 feet of 0.500-inch coaxial cable is indeed 2.479 ohms.
