The Physics behind the Current War: Edison, Tesla, & Westinghouse (AC vs. DC)

Leave a Comment / History of Science / By

In the late 1800s there was a battle between different types of electricity, alternating and direct, that was called the war of the currents, (now a major motion picture starting my boyfriend Benedict Cumberbatch).  There are thousands of videos about this conflict but this is the first, as far as I know, that covers the …
