While an ordinary electrostatic capacitor may have a high maximum operating voltage, the typical maximum charge voltage of a supercapacitor lies between 2.5 and 2.7 volts. Supercapacitors are polar devices, meaning they have to be connected to the circuit the right way, just like electrolyte capacitors.
In comparison, the self-capacitance of the entire planet Earth is only about 710 µF, more than 15 million times less than the capacitance of a supercapacitor. While an ordinary electrostatic capacitor may have a high maximum operating voltage, the typical maximum charge voltage of a supercapacitor lies between 2.5 and 2.7 volts.
However, super capacitors have very small voltage ratings, such as 2.5v, 2.7v and 5.5v (Some common values). This makes things difficult, as in order to make our capacitors capable of charging up to a higher voltage, we need to place them in series, which brings a bunch of other variables into play.
A fully charged capacitor with capacitance C = 50 F and rated voltage VR = 2.7 V has been operated for t = 180 s at constant power output of PC = 0.7 W. How large is the remaining voltage?
