Part a Since you analyzed the charging of a capacitor for a DC charging voltage, how is it possible that you
can apply the analysis when a square wave is applied to the capacitor?
Write out your answer in a clear and well supported paragraph.
Part B
In Part A, (a) why did you set the frequency of the square wave to 0.40 Hz? (b) What would have
happened if you had set the frequency much higher? Much lower?
Write out your answer in a clear and well supported paragraph.
Part C
When discharging the capacitor as in Part B, how many time constants would it
take for the voltage to equal 1.0 % of the initial value or the maximum value Vo?
Explain how your arrived at your answer in a clear and well supported paragraph.

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.
