Why are electrical wires made up of loads of tiny copper fibres instead of one fat copper wire?

Question

Title essentially. What advantage does having loads of fibres have over one solid piece? Flexibility?

In: Physics

Answer 1

Solid wires are not flexible and will break when you try to bend them. So there is an upper limit to the size a cable can be with a single wire before it cannot be used save for very straight run applications.
