What is a pigtail made of?

A pigtail typically refers to a hairstyle where hair is divided into two sections and tied with elastics or ribbons, resembling the shape of a pig's tail. In a different context, such as electrical work, a pigtail can also refer to a short length of wire that connects a device to a power source or a junction box. In both cases, the term "pigtail" describes the way the material is styled or connected.
