A circuit...

i have number to make it easier to point out which is which..
please explain

Thank you

Sapling Learning A circuit (shown to the right) initially consists of a parallel plate capacitor connected to the terminals of a 5.0 V battery. For each of the changes to the circuit detailed below, determine whether the energy stored by the capacitor between points D and E will increase, decrease, or remain unchanged. Increases Decreases Unchanged 2 Another 5.0 V battery is connected between points C and E, with the + terminal connected to C The wire connecting points C and D is replaced with a 2.0 V battery, with the + terminal connected to D Another capacitor is connected between points D and B The area of theThe wire from C to D capacitor's plates are doubled, while its plate another capacitor is replaced by separation is tripled Hint Previous Check Answer NextExit rch 1

Explanation / Answer

1] unchanged as potential will be same.

2] increases as potential increases.

3] unchanged as the potential across the earlier capacitor will remain same as capacitors are in parallel.

4] decreases, because capacitance decreases.

5] decreases as potential across earlier capacitor decreases because capacitors are in series.
