Soldering wire, widely employed in connecting electrical leads, is almost always made of which pair of metals? Correct Answer lead and tin

The most common solders are basically alloys of lead and tin. Most solders contain 30 to 70 percent tin, with occasional minor additions for special purposes. The major application of solders is in production of electrical connections in the electrical and electronics industries.

A telephone switchboard 100 pair cable can be made up with either enameled wire or tinned wire. There will be 400 soldered connections. The cost of soldering a connection on the enameled wire will be P 1.65 on the tinned wire, it will be P 1.15. A 100- pair cable made up with enameled wire cost P 0.55 per linear foot and those made up of tinned wire cost P 0.75 per linear foot. Determine the length of cable run in feet so that the cost of each installation would be the same.
