I have just started reading the book, but already found the common misconceptions (we all learned in school) about the basics of electricity.
One example is “flowing current”. This is actually very confusing, since a current is a flow and not something that can flow.
Also, capacitors store energy, not charge. The charge is there all the time.
Here is one site helping us understand electricity – http://amasci.com/miscon/eleca.html.
