Answer:
definition
Resistivity is the resistance offered by the material per unit length for unit cross-section.
si unit
The SI unit of resistivity is Ohm. meter.
Resistivity
Resistivity increases linearly with temperature. The resistivity of conductors is low when compared to the resistivity of the insulators.
Types
Resistors can be of two types.
Fixed Resistors and Variable Resistors.
