    Input voltage = 120 V
    Output voltage (VL) = 15 V

    It is clear that output voltage will be the peak voltage = (Vp_out) = 15 V
    Input peak voltage (Vp_in) = 120*sqrt(2) = 169.7 V

    Hence, turns ...

    Solution Summary

    "... after filtering through capacitance, there is output dc voltage with ripple (0.1*100/15 = 0.6%)."
