made of the some metal
i) Name the property which is same for both the wires
ii) Name the property which is different for both the wires
iii) If the resistance of wire A is four times the resistance of wire B. calculate
A. The ratio of the cross sectional areas of the wire
B. The ratio of the radii of the wire​

Answer 1

1.resistivity will be same for both
2.resistance will be different for both
3.A ratio of cross section is gl,b
