Ripple for RC Filter

The rms ripple voltage for an RC filter can be approximated by Show and the DC output level by Calculation

Note: These ripple descriptions assume the U.S. standard 60 Hz electrical supply. They can be modified to 50 Hz by examination of the expressions.

Ripple for RC Filter

For = and =   with input peak voltage = V the DC output voltage is = V and the ripple voltage is = mV or = %
