Q.8. Two wires of the same material and same length have radii 1 mm and 2 mm respectively. Compare :
(i) their resistances, (ii) their specific resistance.
Ans. (i) 4 : 1 (ii) 1 : 1
Dear Student ,
Regards
We know,
Resistance, R = ρL/A
A = πr2
So,
R = ρL/(πr2)
In the question the radii of the wires are different . But they are made up of same material and same length.
