Two wires made of same material have lengths in the ratio `1:2` and their volumes in the same ratio. The ratio of their resistances is

Two wires made of same material have their length are in the ratio 1:2 and their masses in the ratio 3:16 . The ratio of resistance of two wires is

Two wires made of same material have their lengths are in the ratio 1:2 and their masses in the ratio 3:16 the ratio of resisstance of law wires is

Two wires A and B of the same material have their lengths in the ratio 1 : 5 and diameters in the ratio 3 : 2 . If the resistance of the wire B is 180 Omega , find the resistance of the wire A.

Two wires A and B of same material have lengths in the ratio 1:2 and diameters in the ratio 2:1. If they are stretched by same force then the ratio of the increase of their lengths will be ----
