The characteristics of five wires are given in the table.
The gauge is a measure of the diameter of the wire;and #18 corresponds to a diameter of 1.2 × 10 - ³ m;and #22 corresponds to a diameter of 6.4 × 10 - ⁴ m.The resistivity of iron is 9.7 × 10 - ⁸ × m;and the value for copper is 1.72 × 10 - ⁸ × m.
-Of the five wires,which one has the smallest resistance?
A)wire A
B)wire B
C)wire C
D)wire D
E)wire E
