Question

define term electrical resistivity of a material
​

Answer 1

Explanation:

The electrical resistivity of a materialis also known as its specific electrical resistance. It is a measure of how strongly a material opposes the flow of electric current. A definition ofresistivity is the electrical resistance per unit length and per unit of cross-sectional area.

Answer 2

it quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows movement of electric charge. Low resistance metals ed copper, require larger currents to produce the same amount of heat. low resistance materials also exhibit low contact resistance .
