The cross section of a bare wire is a square of area 1.00 mm^2 .A 10.0 m, length of this wire is wound close together on a wooden cylinder so that neighbouring coils are completely in contact with each other.There is a total of 200 coils.The resistivity of the material of the wire is 1.0 x 10^-6 ohm meter.estimate the effective resistance of the arrangement .(adsbygoogle = window.adsbygoogle || []).push({});

First of all, i don't really quite understand with the phrase 'cross section of a bare wire is a square' and I want to know whether the 200 coils involved in calculating the resistance.Does the term 'effective resistance' mean using the formulae of parallel resistor as the wire is wounded one after another side by side,(This is my assumption) ?

Thanks for anybody that spend some time on this question and I really hope that somebody will explain to me the doubt I written above.
