Question

Define the term resistivity and state its a unit draw a graph showing variation of resistivity with change in temperature for a typical semiconductor.

Answer 1

resistivity is equal to length of the conductor by area of cross section × resistance it's unit is ohm meters

Answer 2

Answer:

Explanation:

resistivity is just the resistance of a cube of volume 1m^3. it's SI unit is ohm metre.the graph is upward curve with some intercept or we can say starting above from origin
