The external diameter of a 314 m long copper tube is 1.2 cm and the internal diameter is 1 cm. calculate its resistance if the specific resistance of copper is `2.2xx10^(-8)` ohm-metre.

The external diameter of a 5 metre long hollow tube is 10 cm and the thickness of its wall is 5 mm. If the specific resistance of copper be 1.7xx10^(5) ohm-metre, then determine its resistance.

The external diameter of a 4 m long hollow tube is 10 cm and thickness of its wall is 5 mm. If the specific resistance of the copper is 1.7xx10^(-8)Omega m , then calculate its resistance.

When the resistance of copper wire is 0.1 Omega and the radius is 1mm, then the length of the wire is (specific resistance of copper is 3.14 xx 10^(-8) ohm xx m )

When the resistance of copper wire is 0.1 Omega and the radius is 1mm, then the length of the wire is (specific resistance of copper is 3.14 xx 10^(-8) ohm xx m )
