Crash Course Physics #35: How Power Gets to Your Home
In this video [8:33] episode of Crash Course Physics, Shini talks to us about how power gets to our homes. It's kind of amazing when you think about it and much more complicated than it may seem!

Crash Course Physics #36: Ac Circuits
In this video episode of Crash Course Physics, it's time to delve into the world of AC Circuits (or Alternating Currents). We've talked about how they change voltage, which helps transmit electricity over long distances, but there's so...

Khan Academy: Ac Analysis Superposition
We break a sinusoidal input voltage into two complex exponentials. Using superposition, we can recover the complex output signals and reassemble them into a real sinusoidal output voltage. [7:19]

Khan Academy: Ac Analysis Intro 2
Here's a preview of how AC analysis is going to work. To get ready we need to review some of the ideas from trig and complex numbers. [8:57]

Khan Academy: Ac Analysis Intro 1
Solving circuits with differential equations is hard. If we limit ourselves to sinusoidal input signals, a whole new method of AC analysis emerges. [6:42]
