It is hard to imagine a modern culture without electricity. Lights, computers, cell phones, and other modern conveniences are such a central part of our daily existence that the use of electricity is hardly noticed. Most of the items in our lives use a form of electricity called AC which means alternating current. The prevalence of this type of electricity was almost universal until recent technological advances. Now, LEDs, computers, and electric vehicles are all powered by direct current or DC electricity. Today, these two forms of electricity are increasingly interwoven together, but not too long ago, these two types of electricity were the center pieces of one of the most epic societal battles, and it involved two of history’s greatest inventors.
