The war of currents compared the usefulness of alternating versus direct current. As our technology develops, the debate between which current produces the best results continues. The discussions this week will be an exciting deep dive into the differences between AC and DC signal generation, how our energy grid uses these waveforms with transformers, and the many ways we can produce renewable electrical energy.
