Question

A capacitor made of conductive plates (made of metal) is aligned as shown. The plates have a surface area of 2 x 10^-1 m² and are 0.01 m apart from each other. The capacitor is first connected to the voltage source until it is fully charged and produces a potential difference of V0 = 3 kV and then released from the voltage source earlier. If between the two capacitor plates the plastic dielectric material is inserted and fully filling the space between the two plates, the potential difference drops to 1 kV, while the charge on each plate remains. Then specify:

a) Capacitance at initial conditions C0
b) Large Q charge on each plate
c) Capacitance C after the dielectric material is inserted into the capacitor
d) Dielectric constant K on dielectric material
e) Permitivity ɛ of the dielectric material
f) Initial electric field E0
g) Electric field E after the dielectric material is inserted
h) Energy stored in the capacitors before and after the dielectric material is inserted
e) The density of energy stored in the capacitor before and after the dielectric material is inserted

Answer 1

In this question we have to find different parameters related to parallel plate capacitors.
