An empty parallel plate capacitor is connected to a battery that maintains a constant potential difference between the plates. With the battery connected, a dielectric is then inserted between the plates. Does the energy stored by the capacitor increase, decrease or remain the same when the dielectric is inserted? remain the same decrease increase

A parallel plate capacitor with plate separation of 1 millimeter is connected to a battery of 10 volts. If the region between the plates is free space (epsilon_r = 1), calculate the electric field between the plates in Volts/meter, and the electric flux density between the plates in Coulombs/m^2. Suppose a dielectric with dielectric constant epsilon_r = 5 is inserted between the plates. With the battery still connected, calculate the electric field and the electric flux density. Which field has...

A battery is used to charge a parallel-plate capacitor so that the magnitude of the potential difference between its plates is 16.0 V. The capacitor is disconnected from the battery (so the amount of charge on each plate cannot change), and a material with a dielectric constant of 3.49 is inserted between the plates. Find the new potential difference between the plates.

A parallel-plate air capacitor of area A = 21.3 cm2 and plate separation of d = 2.70 mm is charged by a battery to a voltage of 63.0 V. What is the charge on the capacitor? If a dielectric material with κ = 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?
