Answer 2

Answer:

• Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons.
• Resistivity is the physical property of a particular substance which is having particular dimensions.

• Resistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material.
• Resistivity is only proportional to the nature and temperature of the particular material.

• The property of resistance is used in several places like heaters, fuses, sensors, etc.
• Electrical resistivity measurement is used as a quality control test for calcareous soil.
