Answer #1

IP A parallel-plate capacitor has plates with
an area of 1.0×10−2 m2 and a separation of 0.82 mm . The
space between the plates is filled with a dielectric whose
dielectric constant is 1.9.

charge on the capacitor plates is 4.0 μC? Will your answer
to part A increase, decrease, or stay the same if the dielectric
constant is increased?

A parallel plate capacitor has plates with equal and opposite
charges ±Q , which are initially separated by a distance d . The
capacitor is not connected to a battery. Then, the plates are moved
farther apart so they are now separated by a distance 2d and also a
dielectric with dielectric constant κ=2 that fills the entire space
in the gap is inserted. What happens to the stored energy U and the
potential difference between the plates ΔV=V+−V− after...

IP Consider a parallel-plate capacitor

A parallel-plate capacitor is constructed of plates with area
2.5 m2 that are separated by 0.5 mm of air (dielectric constant Ka

to ll the gap between the plates (dielectric constant Kq = 4:3).
Determine whether the energy density of this capacitor increased or
decreased when the quartz was inserted, and by how much.
