A free Khan Academy physics unit introducing electric charge, electric force, electric fields, and voltage (electric potential). It is the first step in a sequence that continues to circuits and electrical engineering.

One commenter highly recommends it as the starting point for learning how electricity works, placed before the Circuits 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].
