Question 3
a. Some materials exhibit the property of superconductivity under certain conditions.
State what is meant by superconductivity and explain the required conditions for the
material to become superconducting.
b. The diagram below shows the cross-section of a cable consisting of parallel filaments
that can be made superconducting, embedded in a cylinder of copper.
copper cylinder
filament
The cross-sectional area of the copper in the cable is 2.28 x 10-7 m². The resistance
of the copper in a 1.0 m length of the cable is 0.075 N. Calculate the resistivity of the
copper, stating an appropriate unit.
State and explain the what happen to the resistance of the cable when the
embedded filaments of wire are made superconductive?
