new 1.5-V AAA battery has a “capacity” (not capacitance) of 1100 mA·h. What does this “capacity” actually represent? Express it in standard SI units. (Express your answer to three significant figures.) 2) How many joules of energy can be stored in the AAA battery?( (Express your answer to two significant figures
For most purposes, we store electrical energy in batteries. But there are drawbacks to batteries: They release their energy rather slowly and are very damaging environmentally. Capacitors would be much cleaner for the environment and can be quickly recharged. Unfortunately they don’t store much energy.
1)A new 1.5-V AAA battery has a “capacity” (not capacitance) of 1100 mA·h. What does this “capacity” actually represent? Express it in standard SI units. (Express your answer to three significant figures.)
2) How many joules of energy can be stored in the AAA battery?( (Express your answer to two significant figures.)
3)At a steady current of 400 mA, how many hours will the AAA battery last? (Express your answer to two significant figures.)
4) How much energy can be stored in a typical 10-μμF capacitor charged to a potential of 1.5 V? (Express your answer to two significant figures.)
5)How does that compare to the energy stored in the AAA battery? (Express your answer to two significant figures.)
