This document provides information on basic electronic components including resistors, capacitors, inductors, transformers, transistors, and diodes. It describes what each component is, how it works, common symbols and values. Specifically, it outlines that resistors restrict current flow and are measured in ohms, capacitors store electrical energy and are measured in farads, and inductors store magnetic energy and are measured in henries. Color codes for resistors and tolerance codes for capacitors are also provided.

- 6. 0 - Black 1 – Brown 2 – Red 3 – Orange 4 – Yellow 5 – Green 6 – Blue 7 – Purple 8 –Grey 9 – White Silver = 10% Gold = 5 %
- 8. Store electrical energy Charges up / discharges Takes time
- 9. multilayer ceramic, ceramic disc, multilayer polyester film, tubular ceramic, polystyrene, metalized polyester film, aluminum electrolytic
- 10. Values - Farads Actually micro-farads for electrolytic Pico-farads for other types XYZ = XY * 10z pF J = 5% K = 10% M = 20%
- 11. Electrolytic capacitors Have a + side and a – side Must wire up the right way around
- 12. Store magnetic energy A wire winding Measured in Henries (H) Normally mH Core Air Iron
