where W represents work done (J), Q is the charge (C) and C is the
capacitance (F). Comparatively higher energy output was observed
on 20th day (31.25 mJ) followed by 10th day (20.80 mJ), 0th day
(12.48 mJ) and 30th day (5.83 mJ) of SBES operation. Observed
results correlated well with enhanced performance of the system
in terms of electricity generation on 20th day of operation.
