Resistor is the equipment/component used to add resistance in the given circuit.
Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction.
R = ρL/A
R = Resistance
ρ = Resistivity of that material/conductor, whichis temperature dependent
L= Length of that material/conductor
A = Cross sectional area of that material/conductor
The SI Unit for Resistance is Ohm (Ω), whereas the SI unit for resistivity is Ohm.meter (Ω⋅m).
