A parallel plate capacitor has a surface area of A = 33.2 cm2 and a plate separation of d = 13.3 mm. How much charge does the capacitor store, when it is connected to a battery supplying a voltage of V = 20.3 V?
How much additional charge flows to the capacitor, when a dielectric material with a relative permittivity of ?r = 5.59 is placed between the plates while the capacitor is kept connected to the battery?
