JimB Super Moderator Most Helpful Member Jan 12, 2008 #2 The question at first sight appears to be badly specified. However: We know the capacitance and the permittivity of the dielectric, so it should be easy to calculate the area of the plates. The resistivity of sheet material is usually specified in Ohm/Square. Square what? you may ask. Just Ohm/Square, think about it. What we dont know is the thickness of the dielectric, but maybe we can make a few assumptions and it doesn't matter, think about it. JimB
