Question

difference between resistance and resistivity

Answer 1

Resistance-It is an opposing force that oppose the flow of electric charge.
Resistivity-Alternative title: specific resistivityResistivity,  electrical resistance of a conductor of unit cross-sectional area and unit length. A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents. High resistivity designates poor conductors.

Answer 2

resistance is the property of a conductor that depends on the material and its geometric properties.
 
resistivity of a material is a specific property of that material  and depends also on the temperature.

Resistance =  resistivity * length of conductor / Area of cross section

Resistance also depends on temperature .

resistivity has units of  ohms-meter.
resistance has units of ohms.
