Two wires of same material have length

L

and

2\,L

and cross-sectional areas

4\,\,A

and

A

respectively. The ratio of their specific resistances would be

View answer and explanation

Correct option: D

\mathrm{1 : 1}

Option D (1 : 1) is correct because specific resistance (resistivity) depends only on the material and temperature, not on the dimensions of the wire.
