Makezine_COTM_Resistors-BadgeMAKE alumnus and supernerd Collin Cunningham rhapsodizes about everyone’s favorite current-fighting backbone of circuitry–the resistor–in this classic MAKE video. Collin talks about Ohm’s Law, resistor color codes, and using pencil graphite to make paper resistors.

    this is typically wonderful from Collin – thank you!

    This is great. If you want more detail about resistor color codes (and a lot else about resistors) go the Analog Devices website and see this in the “Rarely Asked Questions” area:
