telephony

1. Current in a circuit follows a closed loop; not the term "circuit" is derived from "circle". So a signal or power source at one point connected to a load at some other point has two lines or wires to carry the current to the load and from the load; "from" is equivalent to "return". These may be wires or one may be the earth as a path, but the principle remains the same.
2. String a wire between two poles, does not matter what you use it for (carrying signals, power,clothes or just plain looks). Watch it as the wind blows.
3. Do you not know which "end" of a pencil writes and which "end" erases????? Be serious and use your head for more than a hat rack.

Single wire telephone lines were common for "farmer" lines. When the farmer got AC power the lines became noisy due to Induction and ground currents from the AC power.

Open wire lines are subject to momentary short circuits due to the individual wires swinging in the wind. Those "shorts" were also described as "swinging" shorts
