Questions 1. Which has a greater resistance, a 60-watt bulb or a 40-watt bulb? 40- Watts bulb 2. How does the calculated power compare with the rated power of each bulb in parts (1) and (2)? The calculate power is slightly off from the rated power. For a 60-watt bulb the calculated power was 57.6, which is 2.4 less than the rated power. For a 40-watt bulb the calculated power was 42, which is 2 more than the rated power. 3. How does the effective (combined) resistance of the two bulb in parallel compare with their individual resistance? The resistance for the two bulbs in parallel is much less than the resistance of the bulb individual light bulb. 4. How does the combined power output of the two bulbs in parallel compare with their combined rated power? The combined power outlet of the two bulbs in parallel is slightly less than the individual light bulbs combined. 5. When the two bulbs are connected in series, does each lamp draw full power? Can you explain why? When the two bulbs are connected in series they do not draw full power. One of the bulbs
