Consider a plane parallel-plate capacitor made of two strips of aluminum foil separated by a layer of paraffin-coated paper. Each strip of foil and paper is 4.80 cm wide. The foil is 0.00400 mm thick, and the paper is 0.0200 mm thick and has a dielectric constant of 3.70. What length should the strips be if a capacitance of 7.50 ✕ 10−8 F is desired? (If, after this plane capacitor is formed, a second paper strip can be added below the foil–paper–foil stack and the resulting assembly rolled into a cylindrical form—similar to that shown in the figure below—the capacitance can be doubled because both surfaces of each foil strip would then store charge. Without the second strip of paper, however, rolling the layers would result in a short circuit.)
still any doubts feel free to ask at least before giving downvote hope you understand my concerns

1. (3 points) A capacitor consisting of rolled insulator and metal thin strips needs to have a ca- pacitance of 20 nF. The positive and negative terminals are attached to two separate aluminum strips, which act as the parallel plates, and paper, which acts as the insulator is inserted between these. For paper, e 3.5o, and the thickness is 0.050mm. Find the required length of the layered aluminum/paper strip. The width of the layered aluminum/paper strip is 2.0cm. Note that...
