A homemade capacitor is assembled by placing two 9-in. pie pans 7 centimeter apart and connecting them to the opposite terminals of a 6 Volt battery.
a) Compute the capacitance.
b) Compute the charge on each plate.
c) Compute the electric field halfway between the plates.
d) Compute the work done by the battery to charge the plates.
e) Find which of the above values change if a dielectric is inserted?
