Question

Differentiate between resistance and resistivity.

Answer 1

Answer:

Difference between resistance and resistivity.

Resistance :

• Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons.
• Resistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material.
• The SI unit of resistance is Ohms.

Resistivity:

• Resistivity is the physical property of a particular substance which is having particular dimensions.
• Resistivity is only proportional to the nature and temperature of the particular material.
• The SI unit of resistivity is Ohms-meter.
