HOW TO MEASURE RIPPLE AC VOLTAGE?

To measure ripple AC voltage, use an oscilloscope or a true RMS multimeter. Connect the oscilloscope probes across the output where the ripple voltage is present, ensuring proper grounding. Set the oscilloscope to an appropriate time base to visualize the waveform, and measure the peak-to-peak voltage to determine the ripple magnitude. For a multimeter, select the AC voltage setting and connect the leads across the same output to get a reading of the ripple voltage.
