The resistivity of both wires is the same B. The resistance of both wires is the same C. The resistance of wire A is greater than B D. The resistance of wire B is greater than A
A geological core sample is taken at a coal mine. The sample is a cylinder 20.7 feet long and 5.25 inches in diameter. The geologists run electric current through the sample to find its resistivity, which can be used to determine the quality of the coal. A voltage of 5030 V (5.03 × 103 V) is found to produce 11.4 mA of current through the sample. a. What is the resistance in the coal sample? b. What is the resistivity of the sample?
Question A2 Pure copper has a resistivity of 1.68 x 10-8 Nm. Some accurate cubes of copper are prepared, and electrical measurements are made, for which current is passed across a pair of opposite faces. a) Comparing a 2.5 cm cube and a 5 cm cube, which will have the higher conductance? Ex- plain your answer. b) Given eight 1 cm cubes, how can they be stacked to get the highest and the lowest resis- tance between opposite faces of the stack? Calculate the resistance of each stack.
