Solutions to Period 12 Exercises E.1 You have four identical pieces of wire. Each wire is 10 feet long and has a resistance of 1.0 ohm. If you connect the four wires in series, what is their combined resistance? a) 0.25 ohms b) 1 ohm c) 2 ohms d) 4 ohms e) 10 ohms E.1 = d E.2 If you connected the four wires in E.1 in parallel, what would be their resistance? a) less than 1.0 ohm b) equal to 1.0 ohm c) more than 1.0 ohm d) zero ohms e) negative 10 ohms E.2 = a 12-Ex 1&2

E.3 The starter motor on a car draws 60 amps of current at 12 volts. How small must the resistance of each wire of a pair of jumper cables be if the voltage drop along each wire is to be less than 1 volt? a) 0.016 ohms b) 0.20 ohms c) 5.0 ohms d) 60 ohms e) 75 ohms Solve V = I R for R R = V = 1 volt = 0.016 ohms I 60 amps E.3 = a 12-Ex 3
