Question

During the experiment, the capacitor is damaged and needs to be replaced. After rummaging through your tool shed, you realize that you don't have the capacitor of the capacitance you found in (c) and decide to make one by rolling a sheet of paper between aluminum foils. The thickness of paper and aluminum foil is 0.10 mm and 0.02 mm respectively. Find the dimensions of paper and aluminum foil needed for the required capacitance.

Known values:

C(capacitance)= 4.85 microF

T(time constant)= 22.8 ms

R(resistance)= 4.7 kilo

k for paper = 3

k for aliminum = 10.8
