Question

difference between between resistance and resistor

Answer 1

Resistor - component with a mainly resistive behavior when used in an electrical circuit (basically when capacitance and inductance can be considered negligible).

Recistance - a measure of the quantity of this resistive behavior.


hope it helps u

Answer 2

Resistor 
A resistor is an electric  component with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. 

Resistance
Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it.
