Resistance of a wire is directly proportional to the length (l) of thewire and inversely proportional to the area of cross-section of the wire. So, the thicker wire will have more specificresistance as resistivity is directly proportional to area of cross-section.

Two copper wires are of the same length , but one is thicker than the other .

( 1 ) Which wire will have more resistance ?

( 2 ) Which wire will have more specific resistance ?

$\huge\blue{\boxed{\boxed{\mathcal{\bf\purple{♡}{\pink{answer}\purple{♡}}}}}}$

( 1 ) Thinner wire will have more resistance . R ≠ $\frac{l}{A}$ area of cross - section .

( 2 ) Thicker wire will have more specific resistance . Since specific resistance is directly proportional to length .

R = $\frac{Si}{a}$

$\tt{\implies}$ Ra = Si

$\tt{\implies}$ S = $\frac{Ra}{l}$
