In the circuit shown, A & C are identical light bulbs, and B is a differentbulb. It's a 1.5 V battery.5a. If we add another bulb, D, of the same type as A & C, into the sameline as C, what will the potential difference across it be? Why?AB5b. Explain whether bulb D will be brighter, dimmer or the same as bulbC and why.C6a. If the potential difference across bulb A is 1V, then what is the potential difference across bulb B?Explain why.6b. Will bulb A will be brighter, dimmer or the same as bulb B under the simplifying (but impossible)assumption of 100% efficient bulbs where all the energy is output to the environment as light and notheat. Explain why.6c. What, if anything, changes about your previous answer if bulb B is 100% efficient while bulb A is50% efficient (so its energy leaves half as light and half as heat). Explain why.

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.
