Hey!There
Resistance of any substance depends upon their resistivity and their dimensions.R=pl/A where p is resistivity,l is length of conductor and A is cross section of that conductor.Resistivity of copper at 20°C is 1.68×10^-8 ohm-m..You will be given resistivity of conductor.For getting resistance of any conductor substitute value of l and A in above formula..
Ask if any query.
