Question

R ∝ 1, when A and material constant l = length
can anyone explain this in simple words please

Answer 1

Answer:

By the end of this section, you will be able to: ... The resistance R of a uniform cylinder of length L, of cross-sectional area A, and ... Table 1. Resistivities ρ of Various materials at 20º C.

Answer 2

Answer:

Its nothing complicated,

R is resistance... it depends on:

1) Length. (l)   [R ∝ l]

2) Area of cross section. (A)    [R ∝ 1/A]

3) Nature of material.

4) Temperature.
