3. Consider the following scenario: A civil engineering student measures the resistivity of aparticular cylindrical wire for đifferent lengths L by tapping at points the wire from 0.1 m to 1 m in steps of 0.1 m. The radius of the wire is 0.46 mm. The experiment is carried out under following circumstances: 4) The best line has been drawn through the points given below and determine the resistivity of the wire from the slope of the plot between blue marked points. b) Based on the value of resistivity you calculated, what is the material wire resistor made of?

Transcribed Image Text:3. Consider the following scenario: A civil engineering student measures the resistivity of aparticular
cylindrical wire for different lengths L by tapping at points the wire from 0.1 m to 1 m in steps of
0.1 m. The radius of the wire is 0.46 mm. The experiment is carried out under following
circumstances:
a) The best line has been drawn through the points given below and determine the resistivity
of the wire from the slope of the plot between blue marked points.
b) Based on the value of resistivity you calculated, what is the material wire resistor made of?
Make sure everything is in ohms and meters, otherwise your units will not work out correctly
in the end!
