Q: 1. How does the resistance of a 100W light bulb compare
1. How does the resistance of a 100W light bulb compare to the resistance of a 60W light bulb? A. The 100W light bulb has a higher resistance than the 60W light bulb. B. The 100W light bulb has a lo...
See AnswerQ: A 100W light bulb has a resistance of 10 Ω at room
A 100W light bulb has a resistance of 10 Ω at room temperature (2.00 × 101 ◦C). The light bulb is called “100W” because it will dissipate 100W of power when it is connected to a 120 V potential differ...
