Probably more an electronics related query than calc but maybe someone can help...I've got two curves plotted from the equations for charging and discharging a capacitor, both are exponential. Integrating the equations obviously gives me the area under each curve for a given time period. The curves plotted from the equations is time on the x axis and voltage across the capacitor on the y axis. What units is the AUC measured in? I blunderingly assumed volts/sec but that's the derivative not a cumulative total, and I don't think the energy (Joules) or charge (Coulombs) is applicable without the current, which isn't involved in the equation.

My usual go-to guy (Google) doesn't seem to know. Any of the many switched on folk here got any ideas?
