Conclusion:
In this experiment my partner and I were able to understand how a half-wave
and full-wave rectifier functions. Fortunately, we did not run into any issues while
performing the experiment. We were able to view the output waveforms of each
experiment through the oscilloscope and was able to confirm if the experiment was
being performed correctly. Overall, we learned a lot about full-wave and half-wave
rectification through this experiment.
