a) Why in commercial supercapacitors are the equivalent capacitances in the order of tens of Farads, while the values of the resistors are in the order of Ohms?
b) Why if we had to build a prototype in supercapacitor class based on the equivalent circuit would we have to use small values of capacitances?
c) Why do we take into account the charge only of capacitor 2?
d) Why is only a time constant used for the charging time?
