 Connect the oscilloscope so that the voltage after the three-phase bridge can be measured. Sketch the oscilloscope screen image, s. <imgref Fig-19_V3-Screen-image-three-phase-bridge-rectifier-circuit> and label the waveforms with the corresponding voltages. Give the oscilloscope settings used. Connect the oscilloscope so that the voltage after the three-phase bridge can be measured.
