Question

# B. Kitchen Capacitor: Obtain two 8.5 x 11 inch swaths of aluminum foil and three pieces of 8.5 x 11 inch blank paper. Assume the dielectric constant of paper is

2. Complete the following:1) What is the thickness of a single sheet of the paper? (This can be done precisely without measuring the thickness of a single sheet.) Does the thickness of the aluminum foil matter? If so, measure it.2) What is the capacitance of a parallel plate capacitor fabricated from a sheet of раper and the two sheets of aluminum foil? Calculation only. If you roll the capacitor up like a paper towel roll, what must you do extra to have a viable capacitor? Will it have the same capacitance as the parallel plate one? Why or why not?3) Using just the pieces you have, design a capacitor that maximizes one of the following:i) stored charge; ii) permissible operating voltage; iii) stored energy; iv) capacitance. Draw your design, calculate the predicted value. You can fold items as much as you wish, but no more than 6 scissor cuts are allowed.
