Question

Bianca is building a lightning rod to safely conduct lightning strikes away from a building. She should choose a material with high . Talia is manufacturing rolls of wire for hanging pictures. She needs a material that is so that it can easily be pulled into wire without breaking.

Answer 1

The material required by Bianca must have a very high conductivity i.e., low resistivity. Since the lightning rod is required to conduct the electric discharge from a lightning strike away from a building, it must be able to conduct electrons properly.

The material required by Talia must have a high ductility. Ductility is the ability of a material to be drawn into thin wires without breaking. Highly ductile materials are useful for making thin wires for use in electrical appliances and also for binding or hanging structures.
