A super capacitor is to be designed to store the amount of energy that is stored in a typical size C nickel cadmium rechargeable battery. Use (but justify) any reasonable assumptions to calculate the energy that can be stored in the rechargeable battery.(adsbygoogle = window.adsbygoogle || []).push({});

a. Determine the required capacitance value, assuming the capacitor can be charged to 5 volts.

b. Determine the required capacitance value, assuming the capacitor can be charge to 100 volts.

I know that U = .5CV, and we are given V. For a size C nickel cadmium battery, is the potential the same? I'm not sure how to tackle the problem.
