Parallel plate capacitor has an area A=10 m^2 and a separation of 1*10^-4m.
a. What is the capacitance of this capacitor?
b. How much energy is stored in this capacitor when it is charged to a potential of 100V?
c. How much charge is stored on the capacitor?
d. If a material with a dielectric constant e=200 is inserted between the plates of the capacitor and it completely fills the area, what is the capacitance?
