A parallel plate capacitor in air is constructed with a plate area of 7.75cm2 and a plate separation of 0.664mm.

A) Determine the value of the capacitance of this parallel plate capacitor.

B) This capacitor is placed across a 21.0 V battery and allowed to fully charge. What is the value of this charge with included units.

C) When fully charged, what is the energy stored inside the capacitor?

D) With the battery still connected, a pyrex glass dielectric material with dielectric constant K = 5.75 is inserted between the plates, completely filling the space between. What is the new charge stored in the capacitor?
