Question

1. Each plate of a parallel plate capacitor measures 12.0 cm by 18.0 cm. The plates are separated by a distance d = 1.80 mm of air. A 9.00 V battery is connected to the plates. The positive (+) battery terminal is connected to the positive (+) plate and the negative (-) battery terminal is connected to the negative (-) plate.
(a) What is the capacitance of the capacitor?
(b) What is the charge on the capacitor?
(c) How much energy is stored in the capacitor?
(d) What is the electric field between the capacitor's plates?
