ABSTRACT
This section develops some of the basic electrical and electronic principles that we met in the previous chapter. It begins by explaining a number of useful circuit theorems including those developed by Thèvenin and Norton. If you have previously studied Electrical and Electronic Principles at level N (or an equivalent GNVQ Advanced level unit) you should be quite comfortable with this material. If not, you should make sure that you fully understand Section 3.3 before going further!
