What are the main differences between batteries in parallel vs. batteries in series?

  1. 1. The problem statement, all variables and given/known data
    What are the main differences between between batteries in parallel vs. batteries in series?


    2. Relevant equations

    None

    3. The attempt at a solution
    I think batteries in parallel have the same voltage, while batteries in series' voltage adds up with how many batteries you have. What else?
    Does this mean that batteries in series also have a potential for greater power and can make a light bulb brighter?

    Correct - now why would you put batteries in parralel?

    They have greater voltage so for a fixed lamp resistance will provide more current through the lamp and so more power.
