Fwr with filter

Lab example Full Wave Rectifier including Voltage Regulator - Electronic Engineering Technology CCSF Converts 220VAC into DC and uses a filtering capacitor to smooth out the oscillating current. In addition, a voltage regulator is designed to provide constant voltage. See equation to figure out the resistor connected to the voltage regulator. Ripple Voltage (Vr) Limit at 10% of Vmax.
