The 15 Ω resistance copper wire was cut into 5 equal parts and wound from them. Calculate the rope resistance.
Here
from the equation of resistance from which the resistance is
directly proportional to length of conductor and inversely
proportional to area of cross section of conductor.after cutting
and winding to a rope the length and area changes to 1/5th and
5times respectively.comparing 2 cases resistance of rope founded as
