Ripple Factor Formula

Ripple Factor = Root Mean Square Voltage/Positive DC Voltage
r = V_rms/V_cc

How does capacitor reduce ripple?

The ripple can be reduced by smoothing capacitors which converts the ripple voltage into a smoother dc voltage. Aluminum electrolytic capacitors are widely used for this and have capacitances of 100uF or more. The repeated dc pulses charges the capacitor to the peak voltage.
