Question: The plates of an air-filled parallel-plate capacitor each have an area of 0.0095 m2 and are separated by a distance of 1.7 cm. A battery supplies the positively-charged plate with +5.93 x 10-11 C of charge and the negatively-charged plate with -5.93 x 10-11 C of charge.
Question 1: How much energy is stored in this capacitor?
