That sure was Very Pedagogical, with large pictures of components and wires. Nice!
Nitpick: it says that "capacitors are polarized", which is not true in general. There are many kinds of capacitor, some of which are polarized. The electrolyte capacitor in the image is polarized, but I feel there could be a bit more precision in the wording.
