Question

A parallel plate capacitor with a
plate area of 20.0 cm^{2} and plate separation of 8.00 mm
is connected to a constant potential difference of 5.00 V. A
dielectric with a dielectric constant of 4.00 is inserted between
the plates.

a) What is the energy stored in the capacitor?

b) The capacitor is disconnected from the battery and the dielectric is removed from the interior of the capacitor. What is the new energy of the capacitor now?

c) What does this imply in regards to work? Where does this work come from or went into?

Answer #1

A dielectric-filled parallel-plate capacitor has plate area
A = 30.0 cm2 , plate separation d = 8.00 mm and
dielectric constant k = 4.00. The capacitor is connected
to a battery that creates a constant voltage V = 5.00 V .
Throughout the problem, use ϵ0 = 8.85×10−12
C2/N⋅m2 .
Part A- Find the energy U1 of the dielectric-filled
capacitor.
Part B- The dielectric plate is now slowly pulled out of the
capacitor, which remains connected to the battery. Find...
