1. The problem statement, all variables and given/known data Draw a circuit the involves a battery and two identical bulbs that will maximize the lifetime of the battery. More specifically, draw a circuit that allows you to run the lights longest 2. Relevant equations P = IV V = IR Series: R = R1 + R2 Parallel: R = 1/(1/R1 + 1/R2) 3. The attempt at a solution I know that the equivalent resistance of the light bulbs in series is greater than the equivalent resistance in parallel. I also know that the battery provides a fixed emf. In series, there is a smaller current and a larger resistance than in parallel. I think that because parallel circuits have less resistance, if I put the light bulbs in parallel, then the battery life will be maximized. Does this make sense, or am I woefully lost in circuits? Thank you so much.
