Just make sure you’re starting off with a carbon film resistor as this will not work with the metal film variety. His example shows a 10k resistor which is reading just 9.92k on his multimeter.

What’s your favorite value of resistor? 1K? 10K? They’re all fine, but when you need nearly no resistance at all, nothing beats the good old zero-ohm resistor. Wait a minute! Resistors are ...
