1. The problem statement, all variables and given/known data http://nplq1.phyast.pitt.edu/res/westwolf/bookauthor/Capacitors/circle.jpg We use two circular metal plates of radius 0.55 m and thickness 8.7 mm to build a capacitor. We leave a gap of 2.5 mm between the plates and fill half of the space between the plates with a medium with dielectric constant 16.3 and leave the other half filled with air. What is the capacitance of this capacitor in units of nF? 2. Relevant equations C=((eplison zero)*(dielectric constant)*(area))/2 3. The attempt at a solution I'm not sure how to start this problem. I was thinking, maybe divide the area in half, one with the dielectric and one without it, and treat it as two separate capacitors in a series, but can that be done?
