A homemade capacitor is assembled by placing two 9 in pie pans 8 cm apart and connecting them to the opposite terminals of a 9 V battery.
(a) Estimate the capacitance.
_____ pF
(b) Estimate the charge on each plate.
_____ pC
(c) Estimate the electric field halfway between the plates.
_____ V/m
(d) Estimate the work done by the battery to charge the plates.
_____ J
(e) Which of the above values change if a dielectric is inserted? (Select all that apply.)
