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?

A parallel-plate capacitor is constructed of plates with area 2.5 m2 that are separated by 0.5 mm of air (dielectric constant Ka = 1:0006). The capacitor is connected to a 9 V battery and fully charged. The battery is then disconnected, and quartz is inserted to ll the gap between the plates (dielectric constant Kq = 4:3). Determine whether the energy density of this capacitor increased or decreased when the quartz was inserted, and by how much.

A parallel-plate capacitor with only air between the plates is charged by connecting it to a battery. The capacitor is then disconnected from the battery, without any of the charge leaving the plates. A voltmeter reads 44.0 V when placed across the capacitor. When a dielectric is inserted between the plates, completely filling the space, the voltmeter reads 14.5 V . What is the dielectric constant of this material? What will the voltmeter read if the dielectric is now pulled...
