Forget rivers. We're talking electronics. The formula for attaining 63%
of maximum charge (ie. applied VOLTAGE) in terms of time is R*C. The
number of time constants required to approximate full charge is 3. In
order to decrease the amount of time necessary to charge the capacitor,
you must decrease R or C or increase voltage. In the event you increase
voltage, the resultant 63% will be that fraction of a higher voltage.
Increasing current and leaving all other factors even will not decrease
charge time or increase charge per time unit.
