A student working in the physics laboratory connects a parallel-plate capacitor to a battery, so that the potential difference between the plates is 225 V. Assume a plate separation of d = 1.27 cm and a plate area of A = 25.0 cm2. When the battery is removed, the capacitor is plunged into a container of distilled water. Assume distilled water is an insulator with a dielectric constant of 80.0.
(a) Calculate the charge on the plates (in pC) before and after the capacitor is submerged. (Enter the magnitudes.)
before Qi = ___ pC
after Qf = ___ pC
(b)
Determine the capacitance (in F) and potential difference (in V) after immersion.
Cf = ___ F
ΔVf = ___ V
(c) Determine the change in energy (in nJ) of the capacitor.
ΔU = ___ nJ
(d)
What If? Repeat parts (a) through (c) of the problem in the case that the capacitor is immersed in distilled water while still connected to the 225 V potential difference.

A parallel-plate air capacitor of area A=12.0cm2 and
plate separation d=3.80mm is charged by a battery to a voltage
66.0V. If a dielectric material with kappa=3.60 is inserted so that
it fills the volume between the plates (with the capacitor still
connected to the battery), how much additional charge will flow
from the battery onto the positive plate?
