Question

Write an expression connecting the resistance of a
wire and specific resistance of its material. State the
meaning of symbols used.
​

Answer 1

Answer:

Explanation:

resistance R= rho length of cross section/area of cross section

R= RHO L/A

Answer 2

Answer:

R=p L/A

Explanation:

R = resistance of conductor

p= specific resistance of the material of conductor

L = length of conductor

A= area of cross section of conductor
