Introduction

The DC circuit solutions studied up to this point have been accomplished mainly through the use of formulas derived from Ohm's law. Like many other fields of science, electronics has its share of special short-cut methods. These methods, however, must be reserved until enough background theory has been presented to make their use worthwhile. The next sections will therefore be devoted to methods of solution which either simplify circuit calculations, or allow us to solve circuits which cannot be solved by ordinary methods.
