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...
