Multiple Choice
Two wires with the same resistance have the same diameter but different lengths.If wire 1 has length L1 and wire 2 has length L2,how do L1 and L2 compare if wire 1 is made from copper and wire 2 is made from aluminum? The resistivity of copper is 1.7 x 10-5 W·m and the resistivity of aluminum is 2.82 x 10-5 W·m.
A) L1 = 1.7 L2
B) L1 = 0.60 L2
C) L1 = 2.8 L2
D) L1 = 0.36 L2
