Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points The circuit below shows four identical bulbs connected to an ideal battery, which has neg- ligible internal resistance. E A B C D S When the switch is closed, rank the bulbs in order from brightest to dimmest. 1. B = C > A = D 2. A = B = C = D 3. D > C > B > A 4. A = B = C > D 5. A = D > B = C 6. D > B = C > A 7. A = B > D = C 8. A > B > C > D 9. A > B = C > D 10. A = C > D > B 002 (part 2 of 2) 10.0 points Suppose a switch has been added to the circuit as shown. The switch is initially closed. E A B C D S When the switch is opened, what happens to the currents through bulbs A , B , and D ? 1. I A decreases, I B decreases, I D de- creases. 2. I A remains the same, I B decreases, I D remains the same 3. I A increases, I B remains the same, I D decreases. 4. I A decreases, I B remains the same, I D decreases. 5. I A increases, I B remains the same, I D increases. 6. I A remains the same, I B remains the same, I D remains the same. 7. I A decreases, I B increases, I D decreases. 8. I A remains the same, I B increases, I D remains the same. 9. I A increases, I B decreases, I D increases. 10. I A increases, I B increases, I D increases. 003 (part 1 of 4) 10.0 points In the circuit shown below, A , B , C , and D are identical light bulbs....
