Which of the following is an example of neither intrinsic nor extrinsic property?(a) Mass(b) Electrical resistance (Series)(c) Electrical resistance (Parallel)(d) TemperatureI have been asked this question in class test.This key question is from Thermodynamic Preliminaries in chapter Material Balance of Bioprocess Engineering

Answer»

Correct answer is (c) Electrical resistance (Parallel)

To explain: When TWO wires with electrical resistances R1 and R2 are connected in series than the TOTAL resistance is an extensive quantity Rtotal = R1 + R2, but when the wires are connected in parallel the total resistance is not extensive 1/Rtotal = 1/R1 + 1/R2. THEREFORE, electrical resistance is not an extensive nor INTENSIVE quantity.
