resistance dependence

Question

Resistance R of wire length L area A is:

RankGuru · Accepted Answer

The electrical resistance ($R$) of a uniform conductor is:
1. Directly proportional to its length ($L$): $R \propto L$
2. Inversely proportional to its cross-sectional area ($A$): $R \propto 1/A$
3. Determined by the material property called resistivity ($\rho$).
$R = \rho \frac{L}{A}$
