Resistance (R): It is the property of a conductor to resist the flow of charges through it.
• Ohm (Ω): S. I. unit of resistance.
• 1 ohm = 1 volt/1ampere
Resistivity (P): It is defined as the resistance offered by a cube of a material of side 1m when current flows perpendicular to its opposite faces.
• Its S.I. unit is ohm-metre (Ωm).

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 SI unit of resistivity is Ohms-meter.
