A student got a job in the metallurgy industry (metallurgy: study of metals and their properties).

They designed a brand new metal alloy, and were making measurements to determine its basic properties. To measure its resistivity, the student made a wire out of it and connected it to a power supply. A power supply is an instrument that provides power. It displays voltage and current provided.

The student measured the diameter of the wire to be 1.7389 mm. Length of the wire was 161.87 mm. The power supply displayed 0.02225 V and 0.02508 A. What is the resistivity of this new alloy?

• Hint: Remember to convert your units.
• Hint 2: Remember that diameter and radius are not the same thing.
• Do not include units but calculate in base SI
