Question:

Capacitor with a dielectric ?

A capacitor can be made from two sheets of aluminum foil separated by a sheet of waxed paperIf the sheets of aluminum are 0.34 m by 0.31 m and the waxed paper, of slightly larger dimensions, is of thickness 0.03 mm and dielectric constant kappa 2.5, what is the capacitance of this capacitor? answer in nF

Answer:

A0.34 m 0.31 m 0.1054 m^2 k2.5 d310^-5 m e08.85 10^-12 C (0.1054(8.85 10^-12)2.5)/0.310^-5 77.7 nF
Your local building inspectors (or similar) should be able to point you in the right directionyou should be able to get a free inspection.
