Question

When using solder to splice repair wiring, which type should be used?

a) Rosin core
b) 50/50
c) Silver solder
d) Liquid set

Answer 1

For splicing repair wiring, rosin core solder is the recommended type because it contains a flux that facilitates a strong electrical connection and prevents corrosion.

Step-by-step explanation:

When splicing repair wiring using solder, the recommended type to use is rosin core solder. This type of solder is specifically designed for electrical and electronic work. It contains a flux in the core of the solder that helps to remove oxides from the metal surfaces during the soldering process, which allows for a better electrical connection and helps prevent corrosion. In contrast, 50/50 solder, silver solder, and liquid set solder have different properties and uses that may not be suitable for electrical wiring.
