Eli5: Why is it that there are multiple copper wires inside an electric cable and why are they coiled?
In: 68
Stranded copper wire is easier to bend and once terminated it is more vibration resistant.
Solid copper exists though but most people use one or the other because it’s annoying to buy stranded copper wire and solid copper wire the same gauge and color
Solid copper is nice in some circumstances though because it resists bending and bunching up to an extent. It’s also nice for some non electrical tasks like making a make shift zip tie.
