Problem 3:  Consider a parallel plate capacitor having plates of area 1.65 cm2 that are separated by 0.024 mm of neoprene rubber. You may assume the rubber has a dielectric constant κ = 6.7. Part (a)  What is the capacitance in nanofarads?  Part (b)  What charge, in coulombs, does the capacitor hold when 9.00 V is applied across it?

A parallel plate capacitor with air between its plates is charged to 86.6 V and then disconnected from the battery. When an unknown dielectric material is placed between the plates, the voltage across the capacitor drops to 21.519 V. What is the dielectric constant of the unknown material? Assume that the material fills the space between the plates completely. Round your answer to 2 decimal places.

The dielectric of a parallel plate capacitor is to be constructed from glass (Kd= 4.6). The area of each plate is 0.50 m2 . A) What thickness should the glass have if the capacitance is to be 0.10 microfarad? B) What is the charge on the capacitor if connected to a 12-volt battery?

Three capacitors of capacitance C1 = 3.95 µF, C2 = 1.15 µF, and C3 = 6.00 µF are connected in parallel. A %3D potential difference of AVp 22.0 V is maintained by a battery. %3D Find the charge Q stored by the assembly of capacitors. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. µC Find the equivalent capacitance of the assembly of capacitors. µF

K1 K2 A parallel plate capacitor consists of two square plates, each 1.2 cm long on a side, separated by a distance of .48 mm. The top half of the capacitor is filled by a material with a dielectric constant of k1 = 4.7 while the bottom half is filled by a material with a dielectric constant of K2 capacitor. These two capacitors are then in series.] 1.7.
