Hi! I have to build a capacitor out of the following materials: 10 square feet of aluminum foil, 10 square feet of saran wrap (polyvinyl chloride), several sheets of paper, and tape to put it all together. I will only have about 30 minutes to manufacture my design. I have been researching capacitors and so far the best one I have come across using my given materials is a rolled capacitor. Is this accurate? Or is there a better one I have not come across? For this rolled capacitor I would probably only use the foil as my conductor and the saran wrap as my dielectric because, to my knowledge, it has a much higher dielectric strength than paper. The reason I am second guessing my design is because it does not use one of my given materials, paper. Is there a way i could work this in? Or a different design that uses all of my materials? Thanks!!
