Two copper wires have equal length but the thickness of one is twice that of the other. If the resistance of the thin wire is `10 Omega`, find the resistance of the thick wire.

Two wires have same length. But area of cross-section of one is 4 times that of the other. If the resistance of thinner wire be 200 Omega the resistance of the thicker wire is

Two wires are having length , resistivity and their radius in the ratio of 1:3 . Resistance of the thinner wire is 10 Omega , then the resistance of the other wire will be

Two copper wires A and B of equal masses are taken. The length of A is double the length of B. If the resistance of wire A is 160 Omega , then calculate the resistance of the wire B.

The length,radius and resistivity of two wires are each in the ratio 1:3. The resistance of the comparatively thin wire is 20 Omega . Determine the resistance of the other wire.

The lengths radii and specific resistance of two conducting wires are each in the ratio of 1:3. If the resistance of the thinner wire is 10 Omega then the resistance of the other wire will be

Two wires made of same material have equal length and radius of one of them is twice that of the other. Find the ratio of their resistances.
