In this example, we employ the method of coefficients of potential to determine the capacitance on a two-conductor system.

Modules are connected electrically with two-conductor Cinch Jones plugs.

Along with each length of pipe there must be a length of two-conductor wire run from each wall inlet to the central power unit.

Twin-lead cable is a two-conductor flat cable used as a transmission line to carry radio frequency (RF) signals.

If a three-conductor plug is connected to a two-conductor socket, normally the result is to leave the ring of the plug unconnected (open circuit).

Any noise currents induced into a balanced audio shield will not therefore be directly modulated onto the signal, whereas in a two-conductor system they will be.

Two-conductor transmission line (CPW, microstrip, slotline, stripline):

The 3.5 mm or miniature and 2.5 mm or sub-miniature sizes were originally designed as two-conductor connectors for earpieces on transistor radios.

Differential transmission line: A differential transmission line is a balanced two-conductor transmission line in which the phase difference between currents is 180 degrees.

Single-ended transmission line: A single-ended transmission line is a two-conductor transmission line in which one conductor is referenced to a common ground, the second conductor.

In particular if the clamp is closed around a two-conductor cable carrying power to equipment the same current flows down one conductor and up the other, with a net current of zero.

Both two-conductor and three-conductor versions of the three standard sizes are readily available in gender of connectors and fasteners inline versions, and panel-mounting female versions.

Needed are a single-pole electrical switch, a metal wall box and cover plate to contain it and 14-gauge, two-conductor plastic-sheathed electrical cable to link the switch and outlet.

Although most phone hookups can be made with ordinary two-conductor cables or wires, and only two of the four wires are used in most installations, it is best to use the four-conductor cable sold for this purpose.

The separate shield of a balanced audio connection also yields a noise rejection advantage over an unbalanced two-conductor arrangement (such as used in typical home stereos) where the shield must also act as the signal return wire.

This has changed with the introduction of electronic controls, allowing data to be transmitted by two-conductor wire or radio from the loco to a microprocessor on each car, where locally powered valves hold the desired pressure in each brake cylinder.

Of these many varieties, only the two-conductor version with a rounded tip profile was compatible between different manufacturers, and this was the design that was at first adopted for use with microphones, electric guitars, headphones, loudspeakers, and many other items of audio equipment.

The convention was that a two-conductor loudspeaker cable had XLR3 female connectors on both ends, to distinguish it from a three-conductor shielded signal level cable, which has an XLR3 female at one end and an XLR3 male at the other.
