So you want to know what a resistor and a capacitor are? What do those crazy things do? You can check out an open source electronics book online with 6 separate chapters. I have read all of Ch 1 (DC) and Ch2 (AC) and they are phenomenal. The books are available in a variety of formats including HTML and Adobe Acrobat. Below you will find the books available from Prowess Amplifiers.com.
Additional volumes, as well as the chapters in Adobe Acrobat form can be found at:
