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 3 A. 2 pts 02A
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 × 10-8 ohm-meter.
