# Ripple factor

## Description

For the root mean square value of the ripple voltage, the calculation is more involved as the shape of the ripple waveform has a bearing on the result. Assuming a sawtooth waveform is a similar assumption to the ones to calculate ripple voltage (see Ripple voltage) and yields the result to the shown formula.
