24HEEN BLOG – Basic Wire Joining
In this post we will show you how to join and extend wires, we will be using a low power application for our example such as a telephone line (5V DC) or audio speaker cabling.
What diameter of wire (likely copper) is appropriate for your purpose? Well it depends entirely on the maximum current the wire is designed to transmit. Generally speaking low current applications use a narrow wire, whereas high current applications require a large diameter wire. See this guide for more info.
