You see a bird sitting on an electric wire outside your house. You look up the wire specifics at the electric company website and find that the wire is made of aluminum, is 1.75 cm in diameter, and carries a current of 175 A. You estimate that the bird’s feet are a couple centimeters apart. You look up the resistivity of aluminum and find that it is 2.65 x 10-8 Ωm. What is the potential difference between the bird's feet?
Most of the resistance of the human body comes from the skin, as the interior of the body contains aqueous solutions that are good electrical conductors. For dry skin, the resistance between a person’s hands is typically 510 kiloohm. The skin is on average about 2.00 mm thick. We can model the body between the hands as a cylinder 1.60 m long and 12.0 cm in diameter with the skin wrapped around it. What is the resistivity of the skin?

In a physics project, you need a wire to electrically heat a cryostat. You decide to create one with materials you have lying around. You find a 29.0-g piece of copper. The resistivity of copper is 1.68 x 10-8 Ω.m, and its density is 8.9 g/cm3. You will need to use all of your copper to create a solid cylindrical wire that has a total resistance of 0.75 Ω.Determine how long your wire will be, and what its diameter will be.
