The problem is from the 8th edition Cutnell Physics book.Chapter 20, problem 76. My teacher is asking for an additionalcomponent to the problem and I'm not exactly sure how to solve forit. The problem reads: When a light bulb is connected across the terminals of abattery, the battery delivers 24 W of power to the bulb. A voltageof 11.8V exists between the terminals of the battery, which has aninternal resistance of 0.10O. What is the emf of the battery? Whatis the resistance of the lightbulb? I have already solved for the emf, it is 12.0 V, and I knowthat the current is I=2.0338 A. I just need to know how to find thelightbulb's resistance. Thanks!
