a copper wire 750ft long has resistance of 1.563. How long is a copper wire of the same cross-sectional area whose resistance is 2.605. Note: the resistance of these wire is proportional to their length.
attempted to solve:
750ft/1.563=x/2.605
then cross multiply
750 * 2.605 = 1953.750/1.563
= 1250 ft
can someone advise if I am right
thanks
