Two inductance coils made of difference metal wires are haivng the same inductance. But their tume constants are in ratio `1:2`. Then the ratio of their resistances is

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 electrical resistances in the ratio 1:4 if their lengths are in the ratio 1:2 , the ratio of their masses is

Choose correct alternative. Masses of three pieces of wires made of the same metal are in the ratio 1:3:5 and their lengths are in the ratio 5:3:1 . The ratios of their resistances are

Two circular coils are made of two identical wires of the same length. If the number of turns in the two coils are 4 and 2, then the ratio of magnetic inductions at the centre will be

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 circular coils are made of two identical wires of same length and carry same current. If the number of turns of the two coils are 4 and 2, then the ratio of magnetic induction at the centres will be

Two circular coils are made of two identical wires of same length and carry same current. If the number of turns of the two coils are 4 and 2, then the ratio of magnetic induction at the centres will be

Two wires are made up of same material. Ratio of their masses is 1 : 2 and ratio of their lengths is 2 : 1 . So ratio of their resistances is.... .
