I got to thinking about stuff I look up a lot. The resistor color code chart is always nice to have on hand, so I included that. Tolerance is one thing I just don’t have memorized (except for ...

Consequently, the construction (size, shape, and material type) of a resistor determines its resistance value. Four bands are placed on most resistors. When four bands are present: • The first band ...

The Adafruit blog just posted a neat papercraft resistor calculator. If you haven’t yet learned the horribly offensive mnemonic for resistor color codes, now’s your chance to have a cheap and ...
