Get Much Smarter About Electricity in 231 Seconds

Couldn't tell a capacitor from an inductor? This video will teach you, very quickly.

Electricity! We know it when we see it (lightning bolts, the main weapon of Emperor Palpatine, et cetera), but how does it work? For many of us without an electrical engineering degree, it may be a mystery. Luckily, you can fix your ignorance, quickly, with this video from science blogger Tech Adams:

Some of the topics covered:

  • What an electric circuit is, and how to form one
  • The difference between Direct Current (DC) and Alternating Current (AC)
  • The difference between volts, amperes, and watts, and how to calculate all three
  • The basic theory behind resistors, inductors, and capacitors, which in turn forms the basic theory behind everything from circuit boards to electric motors

    If the video moves a little too fast, Tech Adams has also kindly made a static infographic:

    Tech Adam's entire YouTube channel is worth a lunch break or two, with more videos about things like the frame rate of the human eyeball, a brief history of the V-2 rocket, or the tricky question of when you actually turn one (solar) year older.
