Question 8

A parallel-plate capacitor is charged and then remains connected to a constant DC power supply. The distance between the capacitor plates is then slowly increased while keeping the power supply connected.

Which row in the table correctly identifies what happens to the potential difference across the plates and the stored energy in the capacitor?

Potential difference across platesStored energy in capacitor
AStays the sameIncreases
BDecreasesDecreases
CStays the sameDecreases
DIncreasesStays the same
A

Potential difference stays the same; stored energy increases

B

Potential difference decreases; stored energy decreases

C

Potential difference stays the same; stored energy decreases

D

Potential difference increases; stored energy stays the same
