In most residential phone wiring, the cable contains four individual wires. Most phone wire installed in the U.S. during the second half of the 20th century is of the following kind:
Four-strand wire:
The kind of wire shown above has recently become obsolete. For all new telephone wiring projects, you should use Cat 5 cable. All of the Cat 5 wire I've seen uses the following color coding:
In either case, the important point is this: one phone line only requires two of these strands. In the vast majority of cases, the other two wires go unused-- but if you choose, you can certainly use them for a second line (i.e., a totally separate line with its own phone number, which the local phone company will connect to a second terminal in your network interface device). This means that if you are installing a second line for a fax, modem, etc., you usually don't have to actually physically run new wires; you can connect the extra two wires to the second phone line at the network interface device. Assuming that everything is wired properly thruout your house (i.e., nobody has cut corners by not bothering to connect the extra two wires somewhere along the way), this will give you "Line 2" service thruout the house.
If you're going to buy a two-line phone, there's nothing more you need to do, since a two-line phone expects "Line 2" to run on the yellow/black wires. For ordinary phone equipment such a modem, however, you have to convert a "Line 1" jack to a "Line 2" jack. One way you can do this is with a plug-in adapter, but the method described here involves swapping around a few wires in the jack.

Didn't one of those wires carry enough electricity to make that old Bell Phone ring loudly and to light up the dial on the old slimline Phone...
which wire carries the power/juice?

The phone line coming into the house used to be a 2 conductor zip cord.
