Unformatted text preview: 1 3 2 4 12 V A B 6 volts A C B D S 8. Compare the resistance of branch 1 with that of branch 2. A branch is a section of a circuit. The resistance of branch 1 is _____ branch 2. (The resistors are identical) A. Four times B. Double C. The same as D. Half E. One quarter (1/4) Branch 1 Branch 2 3. [5 points total] Compare the relative readings on the ideal ammeters in each of the four circuits (a-d). The light bulbs and the batteries are identical. Explain . 7. In the circuit shown, switch S is initially open. When the switch is closed, what happens to the brightness of bulb A? A. it gets brighter B. it stays the same C. it gets dimmer 8. For the same circuit as in Problem 7, what happens to the brightness of bulb B when the switch is closed? A. it gets brighter B. it stays the same A A A A (a ) (b ) (c) (d ) C. it gets dimmer...
