1. The Effect of Length on the Resistance of the Wire
... decrease. To get the resistance without using Ohm's law you can use the following equation; R = x L A R = Resistance (Ω) = Resistivity (Ω m) L = Length (m) A = Cross Sectional Area (m) This equation allows us to predict the actual resistances of our wires successfully (to a degree) .28 (A = Πr = 6.12x10-8 m) ... 0.6 4.9 x 10-8 x 0.6 6.12 x 10-8 4.77 0.7 4.9 x 10-8 x 0.7 6.12 x 10-8 5.57 0.8 4.9 x 10-8 x 0.8 6.12 x 10-8 6.36 0.9 4.9 x 10-8 x 0.9 6.12 x 10-8 7.16 1 4.9 x 10-8 x 1.0 6.12 x 10-8 7.95 Medium Constantan Wire .40mm length formula resistance 0.1 4.9 x 10-8 x 0.1 1.26 x 10-7 ...
