A two-conductor transmission line supports what kind of transmission?

• A. One-way
• B. Two-way
• C. Intermittent
• D. None

Answer: (B)

Two-conductor transmission lines are designed to carry a traveling wave along their length, with energy moving through the line as voltage and current waves. Because nothing in the line’s structure inherently forces energy to travel in only one direction, signals can propagate toward the load and, if the line is excited or reflected, can travel back toward the source as well. This makes the transmission capable of occurring in both directions, i.e., two-way transmission. One-way transmission would require a unidirectional setup or device that prevents backward flow, which isn’t inherent to a two-conductor line. Intermittent transmission describes sporadic activity, not a fundamental mode of how the line carries signals. None is incorrect because there is indeed the potential for two-way transmission on a two-conductor line.
