part 1 of 8 ✓1 The current passing through the brighter bulb is larger 2. The current passing through both bulbs are the same. Unlike most real bulbs, the resistances of the bulbs in the questions below do not change as the current through them changes. All bulbs considered in this problem are identical. Assume all batteries are ideal (they have no internal resistance) and connecting wires have no resistance. What is true when one bulb is brighter than another? 3. Not enough information is given. 4. The current passing through the brighter bulb is smaller. The current passing through point C is largest. part 2 of 8 A light bulb and a battery are connected as shown in Figure 1. 2. The current is the same everywhere in the circuit. The current passing through point B is largest Figure 1 A The current is the same everywhere except through the bulb. What is true about the current passing through various points in this circuit? The current is the same through AB and larger than through CD. 6. The current passing through point A is largest. The current passing through point D is largest 8. None of these 9 The current is the same through AB and smaller than through CD. 10 The current is the same everywhere except through the battery
The current through A is now twice as large as before. part 3 of 8 Two light bulbs and a battery are connected as in Figure 2. 2. The current through A is now the same as before. 3. None of these B c The current through A is now smaller than before but not half as large. 5. Figure 2 D The current through A is now half as large as before. A Compare the current through A in Figure 2 to the current through A in Figure 1. 6. The current through A is now larger than before but not twice as large. 1. The bulb is brighter than it was before. part 4 of 8 Compare the brightness of the bulb BC in Figure 2 to what it was in Figure 1. 2. The bulb is dimmer than it was before. 3. The bulb is just as bright as before. The potential difference is now larger than before but not twice as large. part 5 of 8 Compare the potential difference across the bulb BC in Figure 2 to what it was in Figure 1. The potential difference is now the same as before. The potential difference is now half as large as before. 3. 4. The potential difference is now twice as large as before. The potential difference is now smaller than before but not half as large. 6. None of these
1. None of these part 6 of 8 Two light bulbs and a battery are connected as in Figure 3. 2. The current through A is now twice as large as before. D 3. The current through A is now half as large as before. 4 Figure 3 A The current through A is now the same as before. Compare the current through A in Figure 3 to the current through A in Figure 1. The current through A is now smaller than before but not half as large. 6. The current through A is now larger than before but not twice as large. 1. part 7 of 8 The potential difference is now twice as large as before. Compare the potential difference across the bulb BC in Figure 3 to what it was in Figure 1. The potential difference is now larger than before but not twice as large. 3 The potential difference is now half as large as before. 04 The potential difference is now the same as before. The potential difference is now smaller than before but not half as large. 6. None of these 1. The bulb is dimmer than it was before. part 8 of 8 Compare the brightness of the bulb BC in Figure 3 to what it was in Figure 1. 2. The bulb is just as bright as before. 3. The bulb is brighter than it was before.
