Half & Full Wave Rectification Guide

Experiment 7 investigates half wave rectification using a diode and capacitor smoothing. The circuit is tested using an oscilloscope to observe the input AC waveform and rectified output waveform. Experiment 8 examines full wave rectification using a bridge rectifier and also tests the effect of adding capacitors for smoothing. The procedures measure and compare waveforms to analyze the effects of the rectification circuits and role of smoothing capacitors.
