Electron Lab provides two valuable capabilities. First, as a teaching aid to learn the colour codes for resistors and inductors. Second, as a utility to find Preferred Values from the various tolerance-based series for the two types of components.

Four-Band, Five-Band, and Six-Band Resistors

Resistor Preferred Value Locator for each of the six series from E6 through E192

Standard and Military Inductors

Inductor Preferred Value Locator for each of the three series from E6 through E24
