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 2500 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 = 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…

Calculate the total capacitance and total charge of the circuit in Figure 1.a. Assume all capacitors are 10 microfarad and 20 V battery as power source.
PLEASE ANSWER BELOW. IT IS A RESEARCH HYPOTHESIS 1. A capacitor was made of aluminum foil strips which were separated by Mylar films. The capacitor was subjected to too much voltage and produced holes in Mylar films. The capacitance was still found to have the same magnitude but the voltage was lesser. Why do you think this happened? 2. Is there any kind of material that when inserted between parallel plate capacitors would reduce its capacitance?
Several capacitors each of different capacitances are connected in series. Which statement below is TRUE? A. The total charge supplied by the battery is the sum of the charges of the individual capacitors. B. The equivalent capacitance of the circuit is the sum of the individual capacitances. C. Each capacitor holds a different amount of charge. D. The total voltage supplied by the battery is the sum of the voltages across each capacitor. E. The total positive charge in the circuit is the sum of the positive charges on each capacitor
