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 when rolled up, the capacitance of the device is twice that when it is not rolled up. If the aluminum is also 0.050mm, estimate the size (diameter/radius and volume) in cm of the cylindrical capacitor What's the maximum voltage at which this device can be connected-explain the reasoning.
