Two parallel square metal plates (side length: 13 cm) are separated by a dielectric material with a dielectric constant 3.9 and a thickness of 2.4 mm. The plates are connected to a 11 V power source and allowed to fully charge.
(a) Find the capacitance of the parallel-plate capacitor (in nF):
(b) Find the charge on the capacitor (in nC):
(c) Find the energy stored on the capacitor (in ?J):
