A student conducted an experiment to measure the electrical resistivity of a metallic wire (39 mm long, 3.7 mm in diameter). Using the four-point method, the student passed a current of 6. mA in the wire and was able to measure a voltage drop of 2.3x107 V between the two ends of the wire. What is the electrical resistivity of the wire (in Q.m)? a. 5.72e-10 b. 9.61e-6 c. 9.61e-9 d. 9.61e-12 e. 2.60e-12 Clear my choice
