Khan Academy's free circuits unit covering basic electrical concepts such as current, voltage, resistance, and simple DC circuits. It is part of a sequence starting with electric charge and fields and leading into electrical engineering.

One commenter recommends it as a basic starting point for learning how electricity works, alongside the related charge and electrical engineering units.

   If you want to begin with the basics then I highly recommend Khan Academy, starting with "Electric charge, field, and potential" [0], then "Circuits" [1], followed by "Electrical engineering" [2].
