Question

VOLTAGE IN SIMPLE DC CIRCUITS AND OHM'S LAW 1. In the circuit below, the battery maintains a constant potential difference between its terminals, points 1 and 2 (i.e., the internal resistance of the battery is considered negligible). The three light bulbs, A, B, and C are identical. a. How do the brightnesses of the three bulbs compare to each other? Explain your reasoning. b. What happens to the brightness of each of the three bulbs when bulb A is unscrewed and removed from its socket? Explain your reasoning. c. When A is unscrewed, what happens to the current through points 3, 4, and 5? Explain your reasoning. d. Bulb A is screwed back in. What happens to the brightness of each of the three bulbs when bulb C is unscrewed and removed from its socket? Explain your reasoning. e. When C is unscrewed, what happens to the current flowing through points 3, 4, and 5? Explain your reasoning. 2. For each of the questions A-E below, a wire is connected from the battery terminal at point 1 to point 4. a. What happens to the brightness of each of the three bulbs? Explain.
