In this example, we are given a plot of current as a function of time while a capacitor charges. We integrate the current plot using software to obtain a total amount of charge (given by the computer in As, but an amp-second is a coulomb. We then use the definition of capacitance as charge per volt (coulombs per volt) to compute the capacitance of the capacitor.
