The quantity that measures taken to reduce the flow of electric current through the material that is said to be the resistance. The formula to determine resistance is:where R is the resistance, resistivity, L is the length of the wire, and a is the section transversal.De the previous formula it is clear that the resistance is dependent on the material of the substance, the length of the wire, and its area of cross-section i.e. resistance is directly proportional to the length of the wire and inversely proportional to the area of the cross section of the wire.Therefore, two wires of properties that offer the greatest resistance to the flow of a stream are long and thin.
