Coaxial cables are ________ lines?(a) Balanced(b) Unbalanced(c) LAN(d) Parallel wire

Answer» Correct choice is (b) Unbalanced

The explanation: Coaxial cables are unbalanced lines; the current in the center conductor is referenced to the braid, which is connected to ground. Coaxial cable and shielded twisted-pair cable provide significant but not complete protection from noise pickup or cross talk from inductive or capacitive coupling due to external signals.
