Resistance Ranking Tasks

Resistance is not futile ... it is voltage divided by current. Scholars apply their knowledge to a series of ranking puzzles. First, they consider wires of varying lengths and then wires of varying cross-sectional areas. Finally, they consider sets of wires that vary by both length and area to finish the lesson that is part of a series on electric circuits.
