Question

The resistance of any uniform conductor is......,Select the proper choice from the given multiple choices.
(A) in inverse proportion to its length
(B) in direct proportion to its length
(C) in the inverse proportion of the square of its area of cross section
(D) in direct proporiton of the area of its cross section.

Answer 1

B is an swer. proportional to length

Answer 2

Answer:

The resistance of any uniform conductor is in direct proportion to its length

Explanation:

R = ρ L / A

R = Resistance of conductor

L = length of conductor

A = Area of Cross Section

=> R ∝ L

The resistance of any uniform conductor is in direct proportion to its length

=> R ∝ 1/A

The resistance of any uniform conductor is in the inverse proportion of the

area of its cross section.
