Question

A parallel plate capacitor with plate separation d is connected to a battery. The capacitor is fully charged to Q Coulombs and a voltage of V. (C is the capacitance and U is the stored energy.) Answer the following questions regarding the capacitor charged by a battery. For each statement below, select True or False.

After being disconnected from the battery, inserting a dielectric with κ will increase U.

After being disconnected from the battery, inserting a dielectric with κ will decrease V.

With the capacitor connected to the battery, increasing d increases U.

With the capacitor connected to the battery, inserting a dielectric with κ will increase C.

With the capacitor connected to the battery, decreasing d decreases Q.

After being disconnected from the battery, decreasing d increases C.

A parallel-plate capacitor with plate separation d is connected
to a battery that provides a potential difference ε. While still
connected to the battery, the plate separation is increased to
2d.
a) Does the potential difference across the capacitor change as
the separation increases? If so, then by what factor? If not, then
why not?
b) Does the capacitance change as the separation increases? If
so, then by what factor? If not, then why not?
c) Does the capacitor charge...

A parallel-plate air capacitor of area A= 14.0 cm2
and plate separation d= 2.20 mm is charged by a battery to a
voltage 56.0 V. If a dielectric material with κ = 4.00 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?

1)A parallel plate capacitor (denoted as Capacitor 1) has a plate
area A1
and a separation distance d1.
It is filled with a dielectric made of mylar (κ=3.1). With these
conditions, it has a capacitance C1.
A second parallel plate capacitor (denoted as Capacitor 2) has the
same plate area as the first capacitor (A1

but the separation distance is twice as large (d1
= ½ d2).
The second capacitor is filled with the same dielectric (mylar) and...
