A parallel-plate capacitor consists of capacitance 5.00 µF.
(i) Determine how much energy is stored in the capacitor when it is joined to a 9.00 V battery?
(ii) When the battery is detached and the distance among the charged plates doubled, determine the energy stored?
(iii) The battery is subsequently re-joined to the capacitor; however the plate separation remains as in part (ii).
Determine how much energy is stored?
