Final answer:
Ductility in metals refers to the ability of a metal to be twisted or bent without breaking. Copper is an example of a ductile metal often used for electrical wiring.
Step-by-step explanation:
Ductility is the ability of a metal to be permanently twisted or bent without breaking. Metals that are ductile can be drawn into thin wires without breaking, making them useful for electrical wiring and other applications. An example of a ductile metal is copper, which is commonly used for electrical wiring due to its high ductility.
