Question 25 • GA-GSE Grade 8 Physical Science

Which properties make a metal a good material to use for electrical wires?

Answer
A
malleability and reactivity
B
conductivity and ductility
C
ductility and malleability
D
reactivity and conductivity

Explanation

A good electrical wire must allow electric current to flow, so the material needs high electrical conductivity. It also needs to be drawn into thin, long strands, which is ductility. Therefore, conductivity and ductility make a metal suitable for electrical wires.
