[-/6 Points] DETAILS MY NOT When we connect a number of light bulbs in a circuit with a battery, we can use our models of current, resistance, and Kirchhoff's principles to predict the relative brightness of the bulbs. If the bulbs are all identical, then the brightness of a bulb will be an indicator of the rrent through that bulb (i.e., a brighter bulb has more current). A Explain your prediction in detail. 1. The bulbs in the circuit shown on the right are all identical. Predict which bulb or bulbs will be the brightest, and which bulb or bulbs will be the dimmest. Also state if any bulbs will have equal brightnesses. B C This answer has not been graded yet. All three bulbs have a resistance of 20 9, and the battery has a potential difference of 9 V. 2. Determine the current through each of the bulbs. Current in bulb A = Current in bulb B Current in bulb C 3. From your answers to part 2, do you think your prediction in part 1 was correct? Why or why not? This answer has not been graded yet. . Suppose that we disconnected bulb C, leaving just bulbs A and B. What would this do to the total resistance of all the bulbs connected to the battery, and would this cause bulb A to get brighter, dimmer, or stay the same? Explain your reasoning.

[-/5 Points] DETAILS If you examine your smartphone battery, you will likely see two numbers: the battery's "capacity" labeled in mAh (milliamps x hours or milliamp-hours), and the battery's voltage or potential difference in V (volts). 1. What physical quantity is the battery's "capacity" measuring? Explain how you can tell. This answer has not been graded yet. 2. Suppose your phone's battery has a capacity of 3500 mAh and a potential difference of 3.8 V. What is the amount of charge, in C (coulombs), that is stored in your smartphone battery when it's fully charged? Charge = 12,600 C 3. Smartphone chargers are usually labeled with their current output in A (amps). Suppose your charger delivers a current of 1.1 A. If your phone's battery is completely drained, how long will it take to fully charge the battery using your charger? Charging time = 3.18 hours 4. Smartphones are advertised with a certain amount of "talk time", i.e., how long the phone's battery will last if you are making a call. If your phone is advertised with 24 hours of talk time, what is the average current coming from your phone's battery while making the call? Average current = A 5. What is the average power output of your phone's battery while you're making a call? Average power = W Viewing Saved Work Revert to Last Response 2.
