An air-filled parallel-plate capacitor has plates of area 2.20 cm2 separated by 2.00 mm. The capacitor is connected to a 15.0 V battery.
(a) Find the value of its capacitance. (pF)
(b) What is the charge on the capacitor? (pC)
(c) What is the magnitude of the uniform electric field between the plates? (N/C)
