A capacitor constructed of two metal plates which are 160 cm long and 4 cm wide. They are separated by a distance fo 0.2 mm, which is filled with an oil that has a dielectric constant (K) of 5.0
a) What is the capacitance of this capacitor?
The capacitor is now attached to a 120 volt source.
b) How much charge will be stored on the plates?
c) How much energy is stored in the capacitor?
