Answer:
For a conductor, the resistance is directly proportional to the length of the conductor and inversely proportional to the area of cross-section. Resistivity is defined as the resistance offered by the material per unit length for unit cross-section.

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. ... Resistivity is only proportional to the nature and temperature of the particular material.
The definition of resistor can be written as: A conductor whose function is to provide a specified resistance in a circuit.
