It's been over a decade since i've sat in a math class.
I can't even remember how to use my graphing calculator.
After searching for formulas on capacitor discharge rate I find myself confused by the symbols (some multi-character). "legends" or "keys" are seldom provided in formula explanations when I search google.
How would I go about calculating the capacitance needed to operate a 208ma load at 5v for 1 second ?
It seems i'd need to plot the discharge and then find an intercept for a lower "threshold" voltage say 3v ?
