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 3100 mAh and a potential difference of 3.7 V. What is the amount of charge, in C (coulombs), that is stored in your smartphone battery when it's fully charged? Charge = |9000 x 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 = 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 = 5. What is the average power output of your phone's battery while you're making a call? Average power = W
