(a) What do you understand by the ''resistivity'' of a substance? (b) A wire is 1.0m long, 0.2 mm in diameter and has a resistance of 10 Omega . Calculate the resistivity of its material?

A wire 1.0 m long, 0.2 mm in diameter, has a resistance of 10 Omega . Calculate the resistivity of its material.

A wire 50 cm long and 0.12mm diameter has a resistance of 4.0 Omega find the resistance of another wire of the same material whose length is 1.5m and diameter is 0.15 mm

The resistance of a wire varies directly with its length and inversely with its area. If a certain piece of wire 10 m long and 0.10 cm in diameter has a resistance of 100 ohms, what will its resistance be if its is uniformly srretched so that its length becomes 12 m?

A wire of length 2.0 m, diameter 1.0 mm has 50 xx 10^-3 Omega (ohm) resistance. Calculate the resistivity of the material of a wire.

A wire of length 1 m and radius 0.1mm has a resistance of 100(Omega) .Find the resistivity of the material .

A wire of length 1 m and radius 0.1mm has a resistance of 100(Omega) .Find the resistivity of the material .

A wire of length 1 m and radius 0.1 mn has a resistance of 100Omega . Find the resistivity of the material.
