A 12 V battery is joined with to a parallel-plate capacitor. Each and every plate has dimensions 5.0 cm × 8.0 cm and the separation of the plates is 1.2 mm. The capacitor is filled with a dielectric of dielectric constant of 2.1.
i) Determine the capacitance? (ii) Determine how much charge is there on each plate? (iii) Determine how much energy is stored in the capacitor?
