You are referrring to the line cord I presume: The cord that connects the telephone set to the jack. A two-wire cord will work for a single-line telephone set. A four-wire cord will support a two-line telephone. If you use a two-wire cord on a two-line telephone set, line two will be dead on the set. A four-wire cord will , of course, work just fine for a single-line set. When you look at the plugs on the ends of the four-wire cord, you will see four small contacts: The middle two are for "line one" and the outer two are for "line two". Sometimes there may me a six-position/contact plug on the ends, with the two outer-most positions not having any wiring connected to them. Line cords also come in 6- and 8- wire configurations for other various types of multi-line analog and digital telephone sets.

How much is the potential difference between the terminals of a connection wire?
The potential difference between the terminals of a connection wire is determined by the voltage difference applied across the wire. This voltage difference creates an electric field within the wire that causes charge carriers to move and establish a potential difference between the terminals.

What is the difference between a black wire and a white wire in electrical wiring?
The difference between a black wire and a white wire in electrical wiring is that the black wire is typically used as the hot wire to carry electrical current, while the white wire is usually used as the neutral wire to complete the circuit and return the current to the power source.
What is the difference between awg and swg?

What constitutes an electric current in a wire?
An electric current in a wire is the flow of electric charge, typically carried by electrons, through the wire. This flow of charge is driven by a voltage difference, or potential difference, between two points in the wire.
What is the difference between a 1 wire and 2 wire alternator?
2 wire has a live wire to energise the field where as the single wire alternator self energises and does not need the powered feed.
