alleryStart learning →Macroscopic properties of materials, including resistivity, are said to depend on their:
AManufacturer and brand
BMolecular and atomic structure
CTotal mass and weight
DSurface colour and finish
Answer & Solution
Correct answer: B. Molecular and atomic structure
1. Bulk electrical behaviour has a microscopic explanation.
2. Resistivity is one of the macroscopic properties of materials.
3. Those properties depend on molecular and atomic structure.
4. So resistivity is a property of the substance rather than the shape alone.
