You are asked to construct a capacitor having a capacitance near 1 nF and a breakdown potential in excess of 10,000 V. You think of using the sides of a tall Pyrex drinking glass as a dielectric, lining the inside and outside curved surfaces with aluminum foil to act as the plates. The glass is 12 cm tall with an inner radius of 3.3 cm and an outer radius of 3.7 cm.
a) what is the capacitance
_______nF
b) What is the breakdown potential of this capacitor?
_______kV
