1. Your friend says that a battery supplies the electrons in an electric circuit. Do you agree or disagree? Defend your answer. 2. Why are the wingspans of birds a consideration in determining the spacing between parallel wires in a power line. 3. When a pair of identical resistors (say 4 ohm each) are connected in SERIES to a 12 V car battery, CALCULATE for both resistors: (a) voltage across each, (b) power dissipated in each, (c) current through each? Do any of your answers change if the resistors are different from each other?
