Electrical engineers sometimes use a wire’s conductance, G = σA/L, instead of its resistance.
a. Write Ohm’s law in terms of conductance, starting with “ΔV = ”.
b. What is the conductance of a 5.4-cm-long, 0.15-mm diameter tungsten wire?
c. A 1.5 A current flows through the wire of part b. What is the potential difference between the ends of the wire?
