QUESTION:
A wire 6.50 m long with diameter of 2.05 mm has a resistance of 0.0290 Ω. What material is the wire most likely made of?
ANSWER:Solution 14E
From the data given, we have to calculate the resistivity of the given material. From this value, we can identify the material. Resistivity of the material can be calculated by the formula, …..(1), where is the resistivity of the material, is its length and A is the area of cross section of the wire.
Given that, length
Diameter
Radius
