where C is the capacitance in Faradays, Q is the amount of charge
obtained (C) and V is the maximum applied potential (Vmax).
Higher capacitance observed on 20th day (251 mF) followed by
10th day (204 mF), 0th day (158 mF) and 30th day (108 mF) of
SBES operation supports the observed higher power generation during
20th day of SBES operation.
