Question

A wire of given material having length 1 and area of cross-section A
has a resistance of 4 Ohm What would be the resistance of another wire
of the same material having length 1/2 and area of cross-section 2A?​

Answer 1

Answer:

may be the answer is one ohm

Explanation:

because wkt R=rho×length%area

so if we substitute the value then,

R=4×1%2 whole divided by 2

R=1 ohm
