Explanation:
Resistance is the property of a conductor to resist the flow of charges through it.
▶ Resistivity is the electrical resistance per unit length and per unit of cross-sectional area. Resistance is the obstruction offered to the flow of current by a conductor. ... And so resistance depends upon the properties of the object.
I hope it may helpful to you so plz marks as brainliest

Answer:
The resistance is the ratio of the length and cross-section area of the conductor, whereas the resistivity of the material is the ratio of the product of the resistance and area to the length of the conductor. ... The SI unit of the resistance is ohm, and the SI unit of resistivity is ohm-meter.
