Question 44 The characteristics of five wires are given in the table below. The gauge is a measure of the diameter of the wire; and #18 corresponds to a diameter of 1.2 x 10-3 m; and # 22 corresponds to a diameter of 6.4 x 10-4 m. The resistivity of iron is 9.7 x 10-8 ohm-meter; and the value for copper is 1.72 x 10-8 ohm-meter. Wire A B D E Material wire C iron wire B copper copper copper iron wire D O None of the given choices Owire A Length 2.0 m 2.0 m 2.0 m 1.0 m 2.0 m Gauge #22 #22 # 18. Of the five wires, which one has the smallest resistance? # 18 # 18 toom Question 43 When a potential difference of 10 V is placed across a certain solid cylindrical resistor, the current through it is 2 A. If the diameter of this resistor is now tripled, the current will be 18 A. 2/3 A. 2/9 A. None of the given choices 3A. 2 pts O 2 A
