(a) Two capacitors can be connected to a battery in either a series or parallel combination. The parallel combination will require (1) more, (2) equal,

(3) less energy from a battery than the series combination.
Why?

(b) Two uncharged capacitors, one with a capacitance of 0.75 μF and the other with that of 0.30 μF, are connected in series to a 12-V battery.
Then the capacitors are disconnected, discharged, and reconnected to the same battery in parallel. Calculate the energy loss of the battery in both cases.
