TOMEWORK FOR LAD O 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 (ie, the internal resistance of the battery is considered negligible) 4 The three light bulbs, A, B, and C are identical. How do the brightnesses of the three bulbs compare to each other? Explain your reasoning, becom hen Senne boghmess a. b. What happens to the brightness of each of the three bulbs when bulb A is unscrewed and removed from its socket? Explain your reasonin c. When A is unscrewed, what happens to the current through points 3, 4, and 5? Explain your reasoning. P3 Currentuncheng ed 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. the 3es beaomes vesyh e, When C is unscrewed, what happens to the current flowing through hin your reasoning
Explanation / Answer
2a) Bulb B will not glow. Bulb A and Bulb C will have same brightness
2b) The current through point 3 increases as the net resistance due to the bulbs decreases
2c) Potential differnece across Bulb B is zero
2d) Potential of point 1 = Potential of point 4
Potential difference across Bulb C = Potential between points 1 and 2
2e)Potential between points 1 and 5 = Potential between points 1 and 2
